In 2025, we finally made the call — Sails.js is out of our stack. We tried hard to keep Sails alive. We added TypeScript, wrote custom types, wrapped controllers, hacked the models, and even considered forking it to modernize the whole thing. But the deeper we went, the more obvious it became — the foundation just isn't made for today. Outdated patterns, broken dependencies, Docker images with critical vulnerabilities... The project is barely maintained — just version bumps for security. It’s no longer a tool for modern development. Our main project today is RestoApp — an open-source platform for restaurants, food delivery, and retail. A big part of it is the admin panel. Originally, we started from sails-hook-adminpanel by Kostya Zolotaryov — and we’re genuinely thankful to him for that. It gave us a solid starting point. Over 8 years, we evolved it a lot — changed frontend stacks multiple times — and today, it’s become a fully independent, configurable, and open-source admin system. No longer tied to Sails, no specific ORM, no locked-in logic. Just a single config file — and it works. Meet Adminizer 📌 What’s next? So yeah — this is our goodbye to Sails. Now — we move forward.  ( 3 min )

"We had the talent. So why were we always behind?" That's when we discovered Agile methodologies - and everything changed. This post is a description of how Scrum and Kanban helped us revolutionize our workflow, and how you can use these frameworks within your web development process, whether you're part of a startup or a large tech team. What is Agile, and Why Should I Care? Traditional "waterfall" methodologies assume requirements don't change and delivery happens at the end. But in web development, anything goes: user needs, features, even entire platforms. Agile embraces this uncertainty. Instead of fixed plans, you focus on ongoing improvement and quick feedback loops. Two of the most popular frameworks within Agile are: Scrum: Works in time-boxed cycles known as sprints (usually 1–2 …  ( 5 min )

We store data to record the state: A password change, an order made, an order delivered and etc. Such things can be seen as stand-alone events or, in many cases, they are part of a step in a process. And, it's common to see those things be chucked into a single table. All those columns can result in models that bloat to 1000s of lines. When looking at a model like that, you may have an urge to group all columns and methods to make sense of what is going on. It's tiring enough doing it once, but it becomes a bigger issue when you and others have to go through the same process each time. In situations like this, proxy models can become invaluable! They can enable you to split columns in models into targeted sections. In this article, I will: Share the basics of what proxy models are Why sho…  ( 5 min )

ORM technology indeed simplifies basic CRUD operations, but it also has many limitations when dealing with complex calculations. Hibernate’s HQL is notably inadequate, making it difficult to implement dynamic column calculations and multi-layer associations. While JOOQ improves flexibility through its DSL, its grouping calculations require multi-layer nesting, leading to more verbose code than native SQL. esProc SPL is like a “plug-in” for data computation! To write a multi-layer JOIN based on dynamic conditions, you had to use chain calls in Java for half an hour with JOOQ. Now you can implement this in just a few lines of SPL script, and its syntax is more intuitive than SQL. For example, calculating ‘top 3 sales by department’, which even requires nesting in SQL: SELECT dept, name FROM …  ( 5 min )

We’re not short on apps. We’re short on quality. On soul. On effing intention. Yeah, I said it. We’re shipping MVPs without asking: Who is this for? Why does this matter? Would I even use this more than once? Half the time, apps today feel like the digital equivalent of a sticky note: quick, forgettable, and destined for the trash. You’ve got a killer stack. You’re running Next.js, Firebase, Tailwind, Gemini APIs, and some fancy prompt-chaining wizardry. Just because you can ship it in 2 days doesn’t mean you should. Real talk: The app store doesn’t need another crypto portfolio tracker. No one is asking for your AI-based meditation timer with 17 onboarding screens. We do not need another damn social app that starts with “Hey! What’s your vibe today?” We need apps that solve real pain. That stick. That respects users' time. Want to Stand Out? Do This Instead.

It’s not new to us, UX & Product Designers, that Figma, while announcing new features in its CONFIG event, is slowly trying to be an Everything Tool to build new digital products rather than being only a tool for Design. And deep down our design, marketing, and development team at Smartters is somewhat supportive of this transition. Historically, Figma has focused on and simplified its features which are most necessary for a UI designer and unavailable on other platforms. From Auto Layout, Multi Select, Variables, and Dev mode to FigJam and Figma Slides, every feature is a hit and brings together different teams of a company, boosting the work pace. This year’s CONFIG 2025 is pretty much the same as every year except for the update. It's the biggest update ever made to Figma. With multiple…  ( 7 min )

We’re living in a time where coding isn’t just about writing lines of syntax anymore — it’s about collaborating with AI to build smarter, faster, and more efficiently than ever. In 2025, AI is no longer a futuristic concept or a fancy buzzword. It’s a daily developer companion — and it’s changing the game. Originally Published on my Hashnode As someone who’s actively learning and building in this space, I’ve seen firsthand how tools like GitHub Copilot, Amazon CodeWhisperer, and others have transformed the way we approach software development.

A Nostalgic Story About 8 years ago, when I was just a kid, I began my coding journey with a school book — you know, the classic QBASIC chapter. I learned about variables, conditional statements, and control flow, writing small programs like basic calculators and whatnot. But then, there was this one section at the end... That single section changed everything. I learned how to draw rectangles, circles, and all kinds of shapes on the screen. And then my brain started buzzing with ideas. You know what’s coming next… my very first game. If you’re a tech person, you’re probably thinking: “Who the hell makes games in QBASIC?” 😅 Well… an innocent 11-year-old me did. I didn’t know how to Google things back then (heck, I barely knew what Google was). But somehow, with a school textbook and sh…  ( 4 min )

JavaScript is evolving faster than your npm dependencies can break. ESNext refers to the bleeding-edge features currently proposed or recently added to the ECMAScript spec — and if you're not keeping up, you're falling behind. In this article, we’ll break down some of the most exciting new features landing in modern JavaScript that are already usable in most major runtimes or via transpilers like Babel or TypeScript. await Outside of Async Functions (Top-Level Await) Previously, await could only live inside async functions. That’s history now. const response = await fetch("/api/data"); const data = await response.json(); console.log(data); Top-level await allows cleaner module code, especially for scripts with dynamic imports or data loading. It’s a game-changer for modular design. ⚠️ W…  ( 4 min )

Ever recorded a great video, only to find the playback looks jittery or rough — especially during fast motion? Whether you’re editing old footage or polishing new content, one thing can instantly improve the experience: higher FPS (frames per second). Here’s why frame rate matters more than you might think, and how modern AI tools like UniFab Video Enhancer AI can help you achieve silky-smooth playback — without re-recording a single second. Why Frame Rate (FPS) Matters FPS determines how many frames appear each second in your video. More frames = smoother motion. 24 FPS – Classic cinematic feel, but can appear slightly stuttery in fast scenes 30 FPS – Standard for web video, balanced and widely supported 60 FPS and above – Ultra-smooth, ideal for sports, gaming, action, or modern so…  ( 4 min )

Description: Learn the basics of key HTML tags and how to build your very first simple webpage with easy-to-follow code examples. Introduction Figure: A historical newspaper front page (Hilo Tribune). HTML stands for HyperText Markup Language, and it’s the foundation of every web page. It uses code (tags inside ) to tell your browser how to display content. This is similar to how a newspaper uses headlines and sections to organize information. For example, the image above shows a newspaper with a big headline and columns of text. In HTML, we create structure with heading tags ( through ) and paragraph tags ( ), just like the title and stories in a newspaper. Why HTML Matters When a browser loads a website, it reads the HTML file to decide what to show. This makes HTML the s…  ( 5 min )

How Java Stores Data in Memory — Primitives vs Non-Primitives Java is a statically typed language, which means every variable’s type must be known at compile time. This allows the JVM (Java Virtual Machine) to allocate memory efficiently and enforce type safety during execution. Primitive types are the building blocks of data in Java. They have fixed memory sizes and are stored in the stack. The value of a primitive can change, but its size does not. Type Size Description byte 1 byte Smallest integer (–128 to 127) short 2 bytes Short integer int 4 bytes Default integer type long 8 bytes Large-range integer float 4 bytes Single-precision float double 8 bytes Double-precision float char 2 bytes Unicode character boolean 1 bit* True or False (handled as 1 byte internall…  ( 5 min )

🚫 Top 10 Common Mistakes in Kotlin Programming Treating nullable types as non-null without checks. ✅ Use ?., ?:, and !! carefully. Prefer safe calls and smart casting. !! (Not-null Assertion) Using !! too much can crash the app with NullPointerException. ✅ Use null-safe operators and proper null checks instead. var Instead of val Declaring variables as mutable (var) when they should be immutable (val). ✅ Prefer val for safer, more predictable code. Using apply, let, also, etc., without understanding context. ✅ Choose the right scope function for the right purpose. == and === == checks structural equality, === checks reference equality. ✅ Know when to use each depending on what you're comparing. Not using try/catch when calling risky operations (e.g., parsing, IO). ✅ Always handle exceptions gracefully. Launching coroutines without a proper scope or dispatcher. ✅ Use structured concurrency: lifecycleScope, viewModelScope, etc. Reinventing functions already available (e.g., filter, map, groupBy). ✅ Explore and master Kotlin’s powerful standard library. Not converting Java-style code to idiomatic Kotlin. ✅ Embrace Kotlin syntax, avoid Java habits (e.g., setters/getters, verbose loops). Explicitly declaring types unnecessarily. ✅ Let the compiler infer types where obvious – cleaner and shorter code. Generate exclusive photo for your post  ( 3 min )

Conceptual Comparison: Developer Mindset, Responsibility Separation, and Task Decomposition Building on the previous article, this one will explore the shift in developers' mindset when transitioning from API development to A2A development. Developer Mindset Shift: Function-Oriented vs. Agent-Oriented. Traditional development often involves thinking in terms of functions or API call sequences: starting from input, invoking services step-by-step, and finally producing output. Developers act as "orchestrators," controlling every step. In contrast, agent-oriented architecture requires a new mindset—designing a community of agents, each responsible for a subtask and interacting via messages and protocols. Instead of scripting flows directly, developers configure systems of autonomous agents,…  ( 5 min )

Understanding == vs Equal() for comparing time When working with time values in Go, one of the most common operations is comparing two timestamps. However, this seemingly simple task can lead to subtle bugs if you're not aware of the differences between using the equality operator (==) and the Equal() method. The equality operator (==) compares all fields of the time.Time struct, including the location information and the monotonic clock reading. This means two times that represent the exact same moment might not be considered equal if they were created in different ways or have different internal representations. t1 := time.Date(2023, time.January, 1, 0, 0, 0, 0, time.UTC) t2 := t1.In(time.FixedZone("UTC-8", -8*60*60)) // These times represent the same instant but have different locati…  ( 13 min )

The first phase of the project, a high-fidelity interactive prototype, is finally complete! This iteration is a sort of detailed rough draft showcasing the design and functionality of the website, mostly using placeholder content. The final straw for this iteration was the addition of the Gallery page. public/gallery/ directory. This means images can be uploaded directly into this folder, and they'll automatically appear with the next site build. To achieve this functionality, the /gallery route is rendered dynamically on the server: export const dynamic = 'force-dynamic'; Rendering the page server-side allows the use of Node's built-in fs module to directly access files on the server: const galleryDir = path.join(process.cwd(), 'public', 'gallery'); let allFiles; try { allFiles = await fs.readdir(galleryDir); } catch (e) { console.error('Could not read gallery directory:', e) allFiles = []; } // Filter to only image files (jpg, png, gif, etc.) const images = allFiles.filter((file) => /\.(jpe?g|png|gif|webp|avif)$/i.test(file) ) I'll be utilizing Statsig to implement feature flags which will allow us to hide and show seasonal Hero sections without interacting with code.

Laravel is one of the most popular PHP frameworks, and for good reason—it's elegant, expressive, and comes with many built-in security features. But just because Laravel provides the tools doesn’t mean you’re automatically safe. Whether you're building an MVP or maintaining a large-scale application, security must be a priority. Here are 15 Laravel security best practices every developer should follow in 2025: Always keep Laravel, its dependencies, and PHP up to date. Laravel releases often include security patches and improvements. Laravel's Eloquent ORM and query builder automatically use prepared statements. ✅ Safe: $users = DB::table('users')->where('email', $email)->get(); ❌ Avoid: DB::select("SELECT * FROM users WHERE email = '$email'"); Escape all output using Blade syntax: {{ $us…  ( 4 min )

As a beginner in C++, you might find yourself needing to convert strings to integers, for which you have already encountered functions like atoi and strtol. While atoi is straightforward, it lacks error checking, making strtol a more robust choice due to its ability to handle conversion errors properly. In this article, we will dive deeper into understanding *temp and &temp when using strtol, clarifying how they work and when to use each. Why Use strtol for String to Integer Conversion? The strtol function is preferred for converting strings to long integers because it provides better error handling. It allows you to detect whether the conversion was successful and if the entire string was converted. Here’s a quick overview of how to use strtol: Prototype: long strtol(const char *nptr, cha…  ( 5 min )

SQL queries are an important tool for retrieving data from databases and are widely used in the field of computer science. SQL stands for Structured Query Language, and many tools can be used to run SQL queries, such as PyCharm and Anaconda Spyder. Below are five essential SQL query concepts that everyone should know. Usage: retrieve specific types of data from a table based on filters. SELECT emp_name Note: Filters are always important, as without them, the data can be overwhelming and may include a lot of unnecessary information. Usage: It is widely used for summarizing data and can be combined with aggregate functions. SELECT department, count(*) AS emp_count Note: Aggregation is useful for identifying patterns and uncovering hidden trends in the data. Usage: Joins are used to com…  ( 4 min )

Here is a quick way to avoid nil errors and get better failures in Ruby and Ruby on Rails. Convert hashes with known keys into Structs: data = { a: 1, b: 2, c: 3} ... MyData = Struct.new(:a,:b,:c) data = MyData.new(a: 1, b: 2, c: 3) Structs will throw if you introduce a typo instead of returning nil. This tightens your feedback loops and reduces debugging time. hash[:d] => nil struct[:d] => in 'Struct#[]': no member 'd' in struct (NameError) That is cool. What about in more fluid situations like user input? You can convert arbitrary incoming hashes into known structs quickly with the following: params = {a: 1, b: 2, c: 3, x: 9, z: 0} MyData.new(**params.slice(*MyData.members)) While Structs have much the same interface as hashes, there are some tricky differences. Hash#each is equivalent to Struct#each_pair. Hash#keys is equivalent to Struct#members. There is no equivalent to Hash#fetch.  ( 3 min )

Key points: New Bitcoin price targets leverage interplay with gold to deliver $200,000 and higher this year. Bitcoin price cycles remain in focus as part of the BTC price “power curve” model. Eating gold’s market cap could propel BTC/USD to nearly $1 million by the decade’s end. Bitcoin (BTC) has a “decent chance” of hitting $250,000 or more in 2025 as attention turns to gold copycat moves.

Blockchain gaming user activity dipped and funding slowed in April, but the overall ecosystem is healthier and maturing, according to blockchain analytics platform DappRadar. User activity dropped 10% over April, with blockchain gaming reaching a 2025 low of 4.8 million daily Unique Active Wallets, DappRadar analyst Sara Gherghelas said in the platform’s April Games Report. Gaming dominance over the decentralized app industry also fell and is now tied with decentralized finance at 21%.  Gherghelas said it’s clear user attention is shifting away from gaming, but under the surface, new infrastructure went live, major publishers doubled down, and high-quality games edged closer to launch.

Ethereum layer-2 scaling platform Starknet has reached a decentralization milestone laid out by Ethereum co-founder Vitalik Buterin and is now the largest zero-knowledge rollup-based network by total value locked. Starknet said in a press release shared with Cointelegraph that it has hit “Stage 1” decentralization, according to a framework Buterin laid out in 2022, which means the network operates with limited oversight or “training wheels.” Starknet added that the framework was the “gold standard onchain tool for analyzing Ethereum scaling solutions,” and said it achieved the milestone through changes such as creating a security council and censorship-avoidance mechanisms.  While the system still allows intervention from a security council, it has implemented a fully functional validity p…

The Pacific US territory of the Northern Mariana Islands has passed a bill allowing its small constituent island of Tinian to launch a stablecoin, overriding an earlier veto by the territory’s governor. The 20-member Northern Mariana Islands House voted 14-2 to undo Governor Arnold Palacios’ April 11 veto of the bill, which allows the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The territory’s nine-member Senate had revived the bill on May 9, voting 7-1 in a two-thirds majority to override the veto, which then needed a two-thirds majority in the House to pass. Representative Marissa Flores (top left) had urged for “thoughtful deliberation” on the internet gaming and sta…

Jason Guthrie, head of product at asset manager WisdomTree, says he’s optimistic despite a noticeable lack of hype that typically comes along with a crypto bull run.  There hasn't been a “really frothy use case that has typically driven these market cycles previously,” such as initial coin offerings (ICOs), non-fungible tokens (NFTs), or DeFi lending, Guthrie told Cointelegraph at Consensus. “This time, we’ve continued to see the asset class gathering value, we’ve continued to see the companies that are built on this technology, growing revenue, growing client bases, continuing to innovate without really hanging their hat on one of these frankly less than useful use cases,” he said.

Deepfake-assisted hackers are now targeting US federal and state officials by masquerading as senior US officials in the latest brazen phishing campaign to steal sensitive data.  The bad actors have been operating since April, using deepfake voice messages and text messages to masquerade as senior government officials and establish rapport with victims, the FBI said in a May 15 warning.  “If you receive a message claiming to be from a senior US official, do not assume it is authentic,” the agency said.   If US officials’ accounts are compromised, the scam could become far worse because hackers can then “target other government officials, or their associates and contacts, by using the trusted contact information they obtain,” the FBI said.  As part of these scams, the FBI says the hackers a…

US federal prosecutors are pressing ahead with their case against Tornado Cash founder Roman Storm, but will drop a small part of their indictment after the Department of Justice rolled back its crypto enforcement last month. Jay Clayton, the acting US Attorney for Manhattan, told federal court judge Katherine Polk Failla in a May 15 letter that the charges against Storm still stand, bar one part of a conspiracy to operate an unlicensed money transmitting business charge. “After review of this case, this Office and the Office of the Deputy Attorney General have determined that this prosecution is consistent with the letter and spirit of the April 7, 2025 Memorandum from the Deputy Attorney General,” Clayton wrote. Deputy Attorney General Todd Blanche’s April memo said the Justice Departmen…

Global foreign exchange and payments platforms are lobbying hard against stablecoins, which stand to significantly disrupt their business models, investor Kevin O’Leary said during a keynote address at Consensus 2025. Legacy forex and payments platforms often extract large fees for servicing cross-border cash transfers and stand to lose out on revenue if regulated stablecoins become accepted as a cheaper, faster alternative, O’Leary said at the Toronto conference.  “Currency trading is a multi-trillion dollar market — and it’s old and ugly and inefficient,” O’Leary said, adding that “[ t]he biggest threat to that monopoly or oligopoly is a regulated stablecoin.”  “Once that’s approved, the multi-trillion dollar FX market becomes efficient, transparent, and inexpensive,” he said.  Kevin O’…

Coinbase chief legal officer Paul Grewal addressed some of the concerns raised by US lawmakers and industry leaders around President Donald Trump’s crypto ventures, and how they may affect related legislation. Speaking at the Consensus conference in Toronto on May 15, Grewal said there had been “hiccups” in Congress since the Senate Banking Committee voted to advance the Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, in March. Though Grewal said there were disputes over “substantial issues that need to be addressed” in the bill, he hinted that Trump’s involvement in the industry was a “complicating factor.”  “The discussion around the president's support for a certain memecoin or two and other efforts does add a certain level of challenge to the effort to g…

There is an ongoing race across the world for Bitcoin accumulation, according to Eric Trump, the second-eldest son of US President Donald Trump.

Asset tokenization is set to accelerate the movement of capital across traditional markets, according to Chainlink co-founder Sergey Nazarov.

Bitdeer Technologies Group reported a 41% year-over-year drop in revenue to $70.1 million for the first quarter of 2025, the Bitcoin miner said on May 15.  The Singaporean company clocked an operating loss of $3.2 million for the quarter, down from a $34.1 million profit during the same period last year, its earnings release said.  However, Bitdeer reported a Q1 net income of more than $400 million, largely driven by gains on convertible notes and warrants issued to stablecoin issuer Tether in 2024.

The slow adoption of stablecoins in Canada has some local crypto industry observers concerned that the country is falling behind. The Canadian Securities Administrators (CSA) classified stablecoins as “securities and/or derivatives” in December 2022 after the FTX debacle that shook markets and turned many lawmakers against the crypto industry. Regulating stablecoins as a security has seen few local stablecoin issuers arise, but in the United States and the European Union, softening regulations have seen significant growth in the stablecoin market. This makes Canada, observers say, less competitive with other jurisdictions.  Of particular concern is the perceived gap in peer-to-peer (P2P) payments in Canada, which stablecoins are uniquely qualified to fill.  Stablecoins globally have grown …

Coinbase has reportedly fired a group of customer support agents following their alleged involvement in social engineering attacks on users. The contracted agents were based in India. According to a May 15 Fortune interview, Coinbase's chief security officer, Philip Martin, said the company flagged customer support contractors who allowed scammers access to user data, suggesting they could be Indian nationals. The CSO’s comments came after some crypto users reeled from attempted phishing attacks using their Coinbase data, which the exchange estimated could cost them between $180 million and $400 million in remediation and reimbursement. Qiao Wang, a core contributor to Alliance DAO, said in a May 15 X post that he may have been a victim of one of these attacks. He said a scammer notified him his Coinbase account had been compromised, asked him to verify his personal information, to which the criminals likely had access through the compromised agents, and requested he withdraw all his funds to a “Coinbase self-custodial wallet.” “I called them out at the end of the call telling them they need to step up their game [...],” said Wang on X. “They told me that had made $7m that day.” Cointelegraph reached out to Martin and Coinbase for comments, but had not received responses at the time of publication. This is a developing story, and further information will be added as it becomes available.

Key takeaways: Spot Bitcoin ETF inflows dropped over 90% from $3 billion to $228 million in four weeks. While strong ETF inflows often drive Bitcoin rallies, recent data shows price movements can occur independently. Despite short-term selling pressure, long-term BTC whale buying suggests a potential continuation of the BTC uptrend. The Bitcoin (BTC) market posted a 90+% drop in spot BTC exchange-traded fund (ETF) inflows, falling from $3 billion in the last week of April to just $228 million this week. Historically, a slowdown in ETF inflows has impacted BTC price, notably when daily inflows averaged over $1.5 billion for consecutive weeks.

Understanding the 10-year Treasury yield: Definition and importance The 10-year Treasury yield is the interest rate that the US government pays to borrow money for 10 years. When the government needs cash, it issues bonds called Treasury notes, and the 10-year note is one of the most watched. The “yield” is the annual return you’d get if you bought that bond and held it until it matures. It’s expressed as a percentage, like 4% or 5%. Think of it as the government saying, “Hey, lend me $1,000, and I’ll pay you back in 10 years with some interest.” That interest rate and the yield move up or down based on demand for the bonds, inflation expectations and the overall economy. Because US Treasurys are considered safe (the government isn’t likely to def…

Key points: US treasuries and foreign capital “repatriation” make a recipe for $1 million BTC, says Arthur Hayes. Europeans face tightening capital controls, inviting a recommendation to take back control of personal funds. Seven-figure BTC price targets are already gaining traction. Bitcoin (BTC) will shoot to $1 million in just three years thanks to global macroeconomic shifts, Arthur Hayes forecasts. In his latest blog post released on May 15, the former CEO of crypto exchange BitMEX doubled down on his sky-high BTC price prediction. Hayes: $1 million Bitcoin due “between now and 2028” Bitcoin has two giant tailwinds that will help propel it to seven digits in just a few years. For Hayes, shifting capital controls worldwide, as well as US treasury “devaluation,” mean that Bitcoin wi…

Prominent short-seller Jim Chanos, once a vocal critic of Bitcoin and cryptocurrencies, revealed a new trading play that involves shorting shares of Strategy (formerly MicroStrategy) and buying Bitcoin. At the Sohn Investment Conference in New York, Chanos told CNBC he’s “selling MicroStrategy stock and buying Bitcoin.” The investor described the move as buying something for $1 and selling something for $2.50, referring to what he sees as a significant price mismatch. Chanos argued that Strategy is selling the idea of buying Bitcoin (BTC) in a corporate structure, and that other companies are following suit in hopes of receiving a similar market premium. Chanos said this was “ridiculous.” He described his trade as “a good barometer of not only just the arbitrage itself, but I think of reta…

Cryptocurrencies and stablecoins are gaining recognition in the traditional finance (TradFi) space for their ability to streamline payments and increase efficiency in existing financial systems In finance, collateral management refers to the process of managing the underlying collateral securing other financial transactions, such as loans or derivatives, to mitigate credit risks and ensure smooth transactions. Digital assets like stablecoins are the “perfect” financial instrument for real-time collateral management, according to a recent pilot by DTCC Digital Assets, which suggests that digital assets, particularly stablecoins, could modernize and simplify this critical function. “Digital assets really are the perfect use case for collateral management, whether it be uncleared derivatives,…

Coinbase, the world’s third-largest cryptocurrency exchange, was hit by a $20 million extortion attempt after cybercriminals recruited overseas support agents to leak user data, the company said. According to a May 15 blog post, Coinbase said a group of external actors bribed and coordinated with several customer support contractors to access internal systems and steal limited user account data. “These insiders abused their access to customer support systems to steal the account data for a small subset of customers,” Coinbase said, adding that no passwords, private keys, funds or Coinbase Prime accounts were affected. Less than 1% of Coinbase’s monthly transacting users’ data was affected by the attack, the company said. Source: Coinbase After stealing the data, the attackers attempted to …

Key takeaways: XRP forms a double top and rising wedge, signaling short-term downside risk toward $1.94. NUPL indicates traders are in denial, resembling past pre-crash phases. Long-term charts still point to bullish targets between $3.69 and $17. XRP (XRP) has rebounded by more than 50% in a month after forming a local low at $1.80.

Private credit marketplace Pareto has introduced a new synthetic dollar aimed at linking institutional investors with decentralized finance (DeFi) opportunities — a move that highlights the expanding role of stablecoins in global finance. The newly launched USP synthetic dollar is fully backed by real-world private credit, Pareto told Cointelegraph on May 15. To mint USP, users must deposit stablecoins such as USDC (USDC) and USDt (USDT), which are then held as collateral. “USP is backed 1:1 by the stablecoins used during the minting process,” Pareto co-founder Matteo Pandolfi told Cointelegraph in a written statement. The deposited funds are placed into Pareto’s credit vaults and lent to what the company describes as “vetted institutional borrowers,” generating yields for participants. To…

Ukraine is reportedly moving closer to adopting Bitcoin as a national reserve asset, a move that could bolster its financial resilience amid the ongoing war with Russia. Lawmakers are reportedly working on a Bitcoin (BTC) national reserve proposal, with a draft bill in its final stages, according to Yaroslav Zhelezniak, a member of parliament who confirmed the plan to local media outlet Incrypted. The proposal was announced during the CRYPTO 2025 conference in Kyiv on Feb. 6. “We will soon submit a draft law from the industry allowing the creation of crypto reserves,” Zhelezniak said. Cointelegraph reached out to Zhelezniak for comment on the bill’s status but had not received a response by publication.

Opinion by: Yat Siu, executive chairman and co-founder, Animoca Brands A discussion on digital property rights, copyright, intellectual property, the open metaverse, AI and value without physical form. When I attend conferences and similar public events, someone almost always approaches me to ask how cryptographic tokens (fungible or non-fungible) can have value even though tokens are virtual and do not exist in the physical world. It's a surprisingly common question, especially one-on-one. Virtual objects like NFTs and cryptocurrencies are both digital and intangible; their existence is not based in the real (physical) world, and (unlike digital currencies) they generally do not have backing by real-world institutions.  The ability to have value (specifically, monetary worth) is crucially…

Key points: Bitcoin has a fight for both $100,000 and a $2 trillion market cap on its hands this month. Dips below six figures are “easily possible,” analyst Filbfilb says, but the odds are stacked in bulls’ favor. ETH/BTC needs to hit the 0.03 inflection point as part of an altcoin comeback. Bitcoin (BTC) is poised for expansion with BTC price action rarely more “bullish-looking,” a popular analyst says. In his latest commentary on X, popular market analyst Filbfilb revealed a key support battle now underway on BTC/USD. Filbfilb on $100,000 battle: “This time is no different” Bitcoin has begun to consolidate after making rapid gains this month, with the area just north of $100,000 seeing “choppy” BTC price moves. For Filbfilb, however, current market behavior is about more than simply…

Key takeaways: Ether’s price fell over 4% to $2,575 on May 15, mirroring similar downward moves across the wider cryptocurrency market.

Several investors of a non-fungible token (NFT) project, Hashling NFT, have accused its founder of misappropriating millions of dollars in profits from the project and a closely tied Bitcoin mining operation. According to the May 14 court filing in Illinois, the plaintiffs allege that their former business partner, Jonathan Mills, lied about transferring assets from Hashling NFT and at least $3 million from the Bitcoin mining project to a holding company — Satoshi Labs LLC (formerly known as Proof of Work Labs LLC), which Mills is the founder and CEO of. The plaintiffs have sued Mills for fraud and breach of fiduciary duty, claiming that they have not received any of the equity returns that he supposedly promised.  They also claim to have raised a combined $1.46 million from two NFT drops …

A Singapore High Court has ruled in favor of Sonic Labs’ motion to force the Multichain Foundation to wind up in an effort to recover funds stolen during a 2023 hack. In the May 9 judgment in the Singapore Supreme Court, Justice Kwek Mean Luck granted a request from Sonic Labs, formerly the Fantom Foundation, to declare Multichain bankrupt and appoint liquidators from global audit, tax and advisory service KPMG. Sonic Labs CEO Michael Kong said in a May 14 statement to X that the team behind the layer 1 Sonic blockchain felt it had no choice but to file a lawsuit to forcibly wind up Multichain because its former employees were being “completely uncooperative” and “hid from victims.” “Going forward, the liquidators can now start working with other parties to initiate the process of trying t…

The US Senate could pass a key bipartisan stablecoin bill as soon as next week after removing language targeting President Donald Trump and his family’s sprawling crypto interests. Republican Senator Cynthia Lummis said onstage at an event by Coinbase’s lobbying arm, Stand With Crypto, that she thinks it's a “fair target” to have the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed by May 26 — Memorial Day in the US. Joining her onstage was Democratic Senator Kirsten Gillibrand, who hinted that the bill’s language was changed to scrap provisions that targeted Trump’s various crypto projects, which include memecoins, a crypto platform, a stablecoin and a crypto mining company that plans to go public, among others. “When this language comes out, peop…

A major Chinese darknet marketplace suspected of facilitating crypto scams and cybercrime has been shut down by the Telegram messaging service, upon which it operated. The internet’s largest illicit marketplace, Haowang Guarantee, formerly Huione Guarantee, said it will shut down following Telegram’s ban of thousands of associated accounts on May 13.  “Since all our NFTs, channels and groups were blocked by Telegram on May 13, 2025, Haowang Guarantee will cease operations from now on,” read the notice on the marketplace website.

Some criminal organizations are yet to receive the memo — crypto is traceable — and could explain the recent string of crypto-related kidnappings, says Chainalysis CEO Jonathan Levin.  Law enforcement has been increasingly successful at tracing stolen funds and crypto ransom payments, resulting in a “lot of arrests,” Levin said during the 2025 Consensus crypto conference, covered by Cointelegraph. “For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” he said.  “Apparently, the know that crypto is not untraceable hasn't been received by some of the organized crime groups that are actually perpetrating these attacks, and some of them are concentrated in, you know, France, b…

Coinbase CEO Brian Armstrong says his firm will continue to look for merger and acquisition opportunities after acquiring crypto derivatives platform Deribit. “We are always looking at M&A opportunities,” said Armstrong on Bloomberg Television on May 14. He added that the firm has a large balance sheet that can be put to use. The firm revealed in its latest revenue report that its balance sheet has strengthened, ending the first quarter with $9.9 billion in US dollar resources. “Part of the benefit of being a public company is, you have a liquid currency to do that,” he said, adding: “We are looking at acquisition opportunities; doesn’t mean we swing at every pitch.

European law enforcement in January arrested 17 suspects of a “mafia crypto bank” who are said to have laundered over 21 million euros ($23.5 million) in crypto for criminal entities in China and the Middle East. The money laundering services were allegedly carried out on behalf of other criminal networks engaged in migrant smuggling and drug trafficking, Europol said in a May 14 statement. Spanish authorities said the criminal organization ran a secret informal money transfer system called hawala and was often compensated in crypto. A total of 17 individuals were arrested — 15 in Spain, one in Austria and one in Belgium — while 4.5 million euros ($5 million) worth of items were seized, including cash, crypto, 18 vehicles, four shotguns and several electronic devices.

Key takeaways: Google search data and app rankings show retail Bitcoin investor demand near 6-month lows. Retail investor interest typically peaks 1 week after BTC breaks all-time highs. Bitcoin (BTC) retail traders are known for entering the market during periods of euphoria, typically after strong monthly gains or a new all-time high. This time is no different, with Bitcoin approaching $104,000 on May 14 while general public interest and retail activity continue to lag. Analysts estimate that in 2025, retail investors were the largest net sellers of BTC, while institutions were the main buyers. But if historical patterns hold, a surge in retail appetite is likely to occur about one week after Bitcoin surpasses the $109,350 mark. Source: X/River According to River’s estimates, individu…

Introduction In Java programming, ensuring the integrity of data being inserted into a database is crucial. If your database is set to utf8 encoding, it limits you to characters within the Basic Multilingual Plane (BMP), specifically from U+0000 to U+FFFF. This means that characters beyond this range, such as emoticons and certain rare characters, will not be supported. To maintain this limit without switching to utf8mb4, it’s essential to validate the input data on the backend. In this article, we'll explore effective methods to perform this validation using regular expressions and Java code examples. Why BMP Character Encoding Matters The BMP is the first plane of Unicode, containing the most commonly used characters in modern languages, music notations, and some symbols. Using the utf8 …  ( 5 min )

Introduction You can use this article as a cheat sheet or a starting point to mastering the CLI. The CLI is one of the most essential tools in a software engineer's toolbox. As useful as it is, it can feel a little intimidating for many developers (especially on the very first encounter). Others get excited. I remember seeing the terminal for the first time and thinking, "whoa, that looks super cool, I want to master it. NOW!" But the CLI wasn't built to impress or scare anyone (especially not scare). It was designed to make our lives easier by providing the simplest form of interface possible. As developers, we should always strive for simplicity—our job is already hard enough without adding layers of unnecessary complexity. The CLI isn't only about simplicity—it's the universal tool. Y…  ( 7 min )

Understanding the Issue The problem of an Android device not appearing in IntelliJ IDEA while being visible in the command line is often due to a configuration or compatibility issue within the IDE or the device's connection settings. The fact that running flutter devices detects your device suggests that ADB is functioning correctly, and your device is connected. However, integ…  ( 5 min )

Many projects start out happily on Auth0’s free tier (up to ~7,000 MAUs), but the jump to the paid Basic plan—\$525/month for 7.5K active users—can sting fast. Beyond raw cost, teams worry about unpredictable bills, feature lock-ins, and vendor dependence. Cloud-Provider Auth Services AWS Cognito, Azure B2C, Google Identity Platform Virtually free until very high volumes, but may lack out-of-the-box UI customization. Backend-as-a-Service (BaaS) Firebase Auth (free up to 50K users/month) Supabase Auth PocketBase (self-hosted) SSOJet, Clerk.dev, Stytch, Kinde All offer generous free tiers and modern SDKs Self-Hosted Open-Source Keycloak, Ory Kratos, Supertokens, Authgear Full control and zero license fees, at the cost of hosting and maintenance overhead. Build-Your-Own Roll your own JWT-based login (e.g., using Passport.js or a simple email/password flow) Simplest for very small scale but requires ongoing security diligence. Scale & Budget: Calculate total cost at your expected growth, not just free-tier limits. Feature Requirements: Do you need MFA, SSO/SAML, social logins, or multi-tenant support? Maintenance Overhead: Self-hosting shifts burden to your team; hosted solutions offload ops at a price. Vendor Lock-In: Check data export and migration paths—some providers don’t let you export password hashes. Community & Support: A vibrant open-source community (Keycloak, Ory) or strong commercial SLAs (SSOJet, Clerk, Stytch) can save you headaches down the road. By weighing cost, complexity, and required features, you can pick a path that fits both your technical needs and your wallet—whether that’s a serverless BaaS, a self-hosted IAM, or even a custom-built solution.

This article will introduce how to import Excel data into MySQL quickly and easily. Here, we prepare an Excel table, as shown below: Open the DiLu Converter tool and create a new database connection firstly. Here we select MySQL database. For a detailed introduction to creating a new database connection, please refer to: Create a new database connection guide After creating a new database connection, click New Import Select the Excel file to be imported and click Start. As you can see, the table fields created by the default are all of the varchar type, which makes the import speed as fast as possible and avoids import failures caused by inconsistency between data and data types. We can also let the tool automatically detect data types . The advantage of this is that the field type can be more consistent with the actual data and make subsequent SQL queries more convenient.

Solana stands out in the blockchain world for its blazing speed and throughput. But to truly unlock that power, developers need to rethink how they build smart contracts. This guide breaks down how to write high-performance, scalable smart contracts tailored for Solana’s unique architecture. Unlike Ethereum’s EVM model, Solana is account-based and parallelizable. Programs (smart contracts) are stateless and immutable. Accounts store the state, data, and are passed into programs explicitly. The runtime can process many transactions simultaneously—if they don’t touch the same accounts. ➡️ Implication: Avoid account contention to benefit from true parallel execution. Rust: The primary language for writing Solana programs. Offers performance, safety, and tight control. Anchor: A Rust-based fra…  ( 4 min )

When working with modern C++ standards in MSVC, developers often encounter unexpected behavior when storing pointers to virtual methods in static inline variables, especially concerning issues with function calls and object lifetimes. In this article, we’ll dig into the reasons behind this behavior, particularly in the context of the provided code snippet, and explore solutions and best practices to avoid pitfalls. Understanding the Issue The issue arises from an ABI limitation related to how MSVC handles virtual methods stored in static inline variables. When you attempt to store a pointer to a virtual function in a static inline variable, MSVC incorrectly resolves the function pointer in some instances, subsequently leading to calls to the wrong function or, in some cases, even the destr…  ( 4 min )

I saw an Object Mapper component is added to Symfony 7.3. Run composer require symfony/object-mapper symfony/property-access to get the needed dependencies. For the people who don't know how Eloquent models work internally. Instead of properties a model class uses an attributes array to identify the fields. I assumed that a custom class that extends PropertyAccessorInterface would be sufficient, because I saw this code in the ObjectMapper class; $this->propertyAccessor ? $this->propertyAccessor->setValue($mappedTarget, $property, $value) : ($mappedTarget->{$property} = $value); So I created the class use Illuminate\Database\Eloquent\Model; use Symfony\Component\PropertyAccess\PropertyAccessorInterface; use Symfony\Component\PropertyAccess\PropertyPathInterface; class ModelPropertyAccess…  ( 5 min )

An AI name generator works by using algorithms—often powered by machine learning or natural language processing (NLP)—to create names that meet specific criteria or patterns. Here’s a breakdown of how they typically function: 🔧 1. Input Parameters Type of name (fantasy, sci-fi, business, product, etc.) Gender (for character names) Language or cultural origin Length or syllables Desired traits (e.g., futuristic, elegant, tough) 🧠 2. Model or Algorithm Rule-Based Systems Good for simple, consistent naming schemes. Limited creativity or adaptability. Markov Chains E.g., if trained on Elvish names, it will produce similar-sounding results. Neural Networks / Language Models Understand phonetics, style, and semantic nuances. Capable of generating unique and creative names that still "fit" a theme. Examples: GPT (like me), LSTMs, or transformer-based models. 🧾 3. Filtering and Validation Check for offensive or inappropriate content Filter by length, pronounceability, or domain availability (for businesses) Remove duplicates or overly similar results 🎨 4. Post-Processing Capitalized or stylized Modified for branding (e.g., removing vowels, adding suffixes like "-ify" or "-ly") Example: Take a dataset of known elf names (e.g., from Tolkien or D&D) Learn common phonemes or structures (e.g., soft consonants, vowel-heavy syllables) Generate something like "Elarion" or "Thalindra" Some of the example of toosls are: Elden Ring Name Generator , Tiefling Name Generator , Khajiit Name Generator  ( 3 min )

First of all, what is it like to have tinnitus? I would say, in short, it sucks. It’s a piece of quality of life that has been lost and you never experience absolute silence again. Can you live with it? Yes! Can you work as a software developer with it? Yes, of course! But it has to be said, a constant, persistent beep is a distraction, especially when a deep focus on a task is needed. I would like to make a few points about how I deal with this, especially when developing software. The first (perhaps most important for me) step in dealing with this was acceptance. In the beginning I felt shame, anger and even fear. However, with the acceptance of this new fact, it got better and my head was clearer again. I looked for nice, relaxing sounds and played them in the background. The beeping is always there, so why not cover it up with something beautiful that you like and brings you joy, I thought to myself. There are countless playlists for all kinds of sounds on the streaming platforms, such as nature and night rain. I take regular breaks and rest my body and mind during this time. In my opinion, a working day, however stressful it may be, should have at least one longer lunch break with fresh air (I’m still working on this). Nevertheless, the lunch break is an integral part of every situation where I don’t think about work for 30 minutes and recharge my batteries. I have already set up my workstation ergonomically. Of course, there’s always room for more. A desk that can be raised and lowered is a great thing. Correct posture is extremely important. I’m still at the beginning in this area and am always looking at where I can improve. Ok ok I know, admittedly sounds, pauses and ergonomics aren’t big new pro tips. I would rather like to say that this impairment loses its power when you exhaust all other possibilities and start optimizing. You should concentrate on the things you can influence and make the best of them!  ( 4 min )

In cache design, we often encounter a troublesome problem: a large number of “invalid queries” put tremendous pressure on the database. For example, when a user requests data that doesn’t exist, we typically query the database, which returns “not found.” If there are many such requests, the database gets busy handling these meaningless queries, affecting system performance. So, is there a way to know in advance whether data “might exist” before querying? This is where Bloom filters come into play. Imagine the following scenario: Our system has a cache layer (Redis) and a database layer (MySQL). When a user requests some data, we first check the cache. If it’s a cache hit, we return the result directly. If the data isn’t in the cache, we query the database. If the database doesn’t have it e…  ( 7 min )

Here's some few developer tools I've used quite a lot these past few months that has made my workflow way more fast & smooth. Most people choose the git cli over GitHub Desktop. TUI (Terminal UI), so you can easily add changes, make commits, deal with branches, revert & rollbacks, etc. And if you have a server running Git (server with TTY - no GUI), you can easily set lazygit up and use it on the go. Checkout lazygit github for some more idea Similar to lazygit, a TUI manager for docker. After using VScode for years now, I tried using Neovim. If you've heard about Vim, it is notorious for being overly complicated for no reason. write, quit, copy, paste. macros. If you wanna test out vim, would recommend Vim Tutor tool While this is not technically a developer tool, anybody can use it. After jumping from one note to google docs to Notion, I settled into obsidian. Its free, has amazing plugin support, and you get this graph of all the notes you have, that's really cool to watch. Tmux is a "Terminal Multiplexer", so suppose you have ssh-ed into a machine, and want to run two foreground process. How do you do that, both in the same terminal? pseudo terminal". That's just one example. Then switch between these terminals with keybindings, which you can customize.

As AI tools become more widely adopted, many teams using Microsoft Azure find themselves asking the same question: What’s the difference between Azure OpenAI vs Azure AI Search? Both sound powerful. Both are part of Azure’s AI services. But they serve very different purposes. If you’re building an AI-driven app, chatbot, or search feature, understanding what each tool does and when to use it can save you time and help you build smarter, faster. Let’s break it down. Azure OpenAI Service gives you access to OpenAI’s language models like GPT-4 and GPT-3.5, hosted securely in Azure.

❌ Top 10 Common Mistakes in Writing Scripts Using fixed paths, IPs, or credentials inside the script. ✅ Use variables or config files instead. Assuming user input or arguments are always correct. ✅ Always check for type, format, and range. Ignoring exceptions or command failures. ✅ Use try/catch, if [ $? -ne 0 ], or similar. Leaving behind unused logs, temp data, or cache. ✅ Add cleanup functions or use trap in shell scripts. Continuing the script even when a step fails. ✅ Always check exit codes before moving forward. Using vague variable or function names (x, temp, data1). ✅ Use descriptive and consistent naming. Forgetting loop conditions or exit criteria. ✅ Always define clear limits and break conditions. No comments, no usage instructions. ✅ Add inline comments and a help section (--help flag). Writing credentials directly in the code. ✅ Use environment variables or secure vaults. Running scripts directly in production without testing. ✅ Always test in a sandbox or staging environment first.  ( 3 min )

Introduction If you're building an app in Android Studio and facing the error message, 'Unresolved reference: Offset', you're not alone. This issue commonly occurs when using the Relay plugin to import designs from Figma, and it can be quite frustrating. The IDE (Integrated Development Environment) may suggest an import for androidx.compose.ui.geometry.offset, but this file seems to regenerate with each build, leading to confusion. This piece aims to elucidate why this occurs and how to effectively resolve the problem. Why You Encounter This Issue The 'Unresolved reference: Offset' error typically indicates that the compiler cannot locate the class or library you are trying to utilize. In Kotlin, particularly when dealing with Jetpack Compose, the Offset class is part of the androidx.compo…  ( 5 min )

The Vaudeville era, a golden age of variety entertainment, holds a special place in the history of American theater and popular culture. Spanning from the late 19th century to the early 20th century, Vaudeville shows combined music, comedy, magic, and acrobatics in an energetic, fast-paced format. These variety performances were integral to the entertainment landscape, influencing modern-day television, theater, and even stand-up comedy. Today, the Vaudeville tradition lives on through the legacy of performers and acts that defined a unique era in the performing arts. Vaudeville was a theatrical variety show that became immensely popular in the United States during the late 1800s and early 1900s. It featured a wide range of acts, from singers and dancers to comedians, magicians, ventriloqu…  ( 6 min )

When I first encountered the term “Service Principal”, I was completely confused. If you’re getting started with cloud infrastructure, especially in Azure, the concept of a Service Principal can feel vague and overly abstract. You’re not alone — many professionals, especially those coming from traditional development or sysadmin backgrounds, struggle to understand: What exactly is a Service Principal? When and why should you use one? In this post, I’ll break it down in plain language, using real-world example and code snippets— so by the end, you’ll never be confused by the term again. Service Principal is like a user account for apps or services that need to access Azure resources. For example in order to login in the system user need user name and password, similarly its kind of user nam…  ( 4 min )

🐳Docker Basics: Containerizing Your First Web App Ever had a web app work perfectly on your laptop but completely break on someone else’s machine? Welcome to the infamous "it works on my machine" problem. Docker helps you solve that — by letting you package your app, dependencies, and environment into a portable container. In this blog, I’ll walk you through how I containerized a simple Flask web app, step-by-step. What is Docker and Why Should You Care? Docker is a tool that makes it easy to create, deploy, and run applications by using containers. A container bundles everything your app needs to run — code, libraries, and settings — into one neat unit. This means it will behave exactly the same on any machine that supports Docker. If you're a student or grad getting into development, De…  ( 4 min )

In Angular development, creating custom form components is a powerful way to encapsulate logic and maintain reusable UI elements. However, when integrating these components into Angular’s form ecosystem, many developers ask: ControlValueAccessor , or is *FormGroupDirective * more appropriate for this use case? ✅ Use ControlValueAccessor for Single Form Control Components If your custom component represents a single form control — such as an input field, toggle switch, dropdown, or similar —the correct and most idiomatic approach is to implement the *ControlValueAccessor * interface. You're building a custom input with a prefix and suffix icon: Since this component only handles a single value, ControlValueAccessor is the ideal…  ( 4 min )

Introduction The focus of this article is to run multiple services on a single port, such as hosting two websites on port 80 and port 443. As we all know from the facts that in a system there are total 65536 ports that is from 0 - 65535 ports that are being used, out of this many are system reserved ports and only small amount of ports are available on which we can expose services. Such as port 80 for HTTP, 443 for HTTPS, 22 for SSH , 3389 for RDP and so on. By default every system has at least 2 network cards, one is the loopback or the localhost network card (127.0.0.1), and another one would be either WiFi or the LAN network card (192.168.1.1). This can be checked using the command ipconfig if you are using the windows system or if you are Debian/Ubuntu distribution use ifconfig. I h…  ( 4 min )

Hey dev.to community! I was recently learning a few SecOps topics and was trying things out with the tool StackStorm (it's basically a ITTT tool for devops) that helps in event-driven automation.

Introduction When backloading data from a SQL Server table into a DB2 table, you might encounter errors related to null date columns. A common issue is the error message: "Operand type clash: int is incompatible with date". This happens when the data types between the source and destination databases don’t align properly, especially for nullable date columns like ACTUAL_CLOSED. In this article, we'll explore the reasons for this issue and provide effective solutions. Understanding the Issue Why Does the Operand Type Clash Occur? The operand type clash error occurs because SQL Server treats a null date value in certain contexts as an integer zero (0). When this zero gets transferred to DB2, it creates a type inconsistency since DB2 expects an actual date value, not an integer. The use of te…  ( 5 min )

Ever pushed an API key to production? Don’t lie—we’ve all done it. Here’s how to make sure it never happens again, using a 10-line Vite plugin. Secrets don’t belong in your codebase. Not in a commit, not in a PR, and definitely not in production. And yet, it happens—a quick console.log() with an API key, a test token dropped into a config file, a placeholder password that never gets removed. Days later? Still there. Weeks? Maybe it even gets pushed to production. I've heard more than one story of dev teams scanning older, inherited codebases—only to find hardcoded API keys sitting in plain text. These weren’t new mistakes, they’d been buried for years. It’s a reminder that even quiet, untouched code can hide serious risks.

Introduction As someone with nearly twenty years of experience, I've helped teams understand how their systems perform under pressure. I can tell you this: most load tests don’t fail because there aren’t enough users. And one of the biggest blind spots? Compatibility. You can run a well-designed test, simulate 10,000 users, and hit all your APIs. But you might still miss that your front-end has issues on Safari. Or, your mobile users can’t finish the checkout process. This isn’t just about performance. It’s also a compatibility problem. When you add more users, this issue becomes a performance problem. In the early days of testing, compatibility was about making sure your layout didn’t break in Netscape. As applications changed to single-page apps, mobile-first designs, and multi-device…  ( 6 min )

Basically there are 3 types: Basic Authentication, Bearer Authentication and Cookie Authentication.

Besides that, I mention some connected topics to keep in mind without going into more detail and I have a quick code snippet as well. The simplest and oldest type - but it's insecure. So do not use it, just know about it. It's been in HTTP since version 1 and simply includes the credentials in the request: Authorization: Basic As you see, we set the HTTP header Authorization to the string username:password, encode it with base64 and prefix Basic. The server then decodes the value, that is, remove Basic and decode base64, and then checks if the credentials are c…  ( 5 min )

Kitty - A secure, encryption-focused configuration management tool written in Rust I built Kitty to solve a problem I faced while managing configuration files across servers: I wanted Git-like tracking for system config files, but with built-in encryption and the ability to keep files in their original locations. What is Kitty? Secure configuration management tool with Git-like commands Files remain in their original locations (no need to symlink like with dotfiles managers) All stored content is encrypted with ChaCha20-Poly1305 Password-protected repository access Choose between file-based or SQLite storage Works with system files that might require elevated privileges Core features: Track, version, and restore configuration files See differences between tracked and current versions Filter and group tracked files Restore previous versions when needed Privilege handling for system files Kitty is designed for sysadmins, DevOps engineers, and anyone who wants to securely track configuration files without moving them into a Git repository. The project is open source and written in Rust. It focuses on security first, with all sensitive content encrypted, making it suitable for tracking credentials and other sensitive configurations. GitHub repo: https://github.com/kometen/kitty I'd love feedback from the HN community, especially on the security model and additional features that would be useful for your configuration management workflow.  ( 3 min )

Note: I am primarily using this as a study tool as I'm upskilling my foundational knowledge. With this in mind, this document is ongoing, and I'll likely be updating it weekly. Opening and closing tags: Note: omitting the closing tag at the end of a file can be beneficial so you don't have any unwanted white space at the end of the file Printing: echo 'This prints to the screen.'; Commenting: One line: # This is a one-line comment in PHP Multi-line: /* This is a multi- line comment in PHP */ Checking variable type: var_dump($var_name); Comparing Floats: Note: Comparing floats in PHP is tricky because of precision. The following is a workaround for that limitation. String Definitions: 'this is a string' "this is a string" or echo 'this line prints a {$var}'; String concatenation uses a . rather than a + in PHP. I used PHP's documentation as the source of my information here. Some of the code will be similar or identical.  ( 3 min )

Logs are your primary tool for understanding what your API is doing in production. But many developers fall into two extremes: Too little logging, and you're blind in production.

Laura Kankaala, Head of Threat Intelligence, F-Secure Cyber criminals have made scamming a trillion-dollar business. As technology and the internet evolve, so do scams, making them the biggest threat consumers face every time they go online or use their phone. While organizations have been trying to keep up with scammers by employing different types of cybersecurity approaches and frameworks, that same focus has been missing in consumer cybersecurity - until now. The cybersecurity industry often focuses on specific instances of scams, like someone pretending to be Brad Pitt on a dating app, or a user accidentally clicking on a malicious social media ad. We also seem to focus a lot on the psychological aspects of a scam, like certain manipulation tricks that are employed. But putting too mu…  ( 5 min )

I've learned it the hard way... If you use the recently released Grok-3 Mini reasoning model (which is great by the way) you might have your token usage reported wrong... While both OpenAI and xAI report reasoning usage in usage.completion_tokens_details.reasoning_tokens field: OpenAI includes reasoning tokens in usage.completion_tokens xAI doesn't include Hence for OpenAI (and according to my tests for Deepseek R1) in order to get the total tokens you can use the old good completion_tokens field. With xAI you need to add up the 2 values to get the right totals (and get you cost estimations correct). Neither litellm nor AG2 (out of recently used LLM libs) adjust the reported usage for that Grok's quirk. Grok API provides a compatible OpenAI endpoint. For reasoning models the didn't invent the wheel and use the standard reasoning_effort parameter just like OpenAI does with its' o1/o3/o4 models. Yet for some reasons xAI decided to deviate from OpenAI's approach to reasoning tokens accounting. That's unfortunate this inconsistency got into prod API from xAI.  ( 3 min )

This-driven development, that-driven development, and now you should bother with this other thing? I am only half-serious. You should not. Yet you might still want to consider it as a litmus test for your projects. I am not saying that you should use Software Development Kits (SDKs) for development. We all do. Rather, I am asking you to think of your codebase and product as an SDK or part of it. But first, what is all this XYZ-driven development? XYZ simply refers to the guiding principle or artifact that drives the development process. Mind you, this is not necessarily a methodology like "Agile" or "Waterfall", which drive the organization of the development process.

Ever tried using a mobile app that felt... off? Maybe the buttons didn’t respond quite right, or it lagged at the worst moment, like when you were about to hit "confirm" on a payment.

Hoisting is a fundamental concept in JavaScript that often leads to confusion, especially for those new to the language. Understanding how hoisting works can help you write cleaner and more predictable code. This article explains what hoisting is, how it works, and the differences in behavior between various types of declarations. Hoisting is JavaScript’s default behavior of moving declarations to the top of their scope before code execution. This means that variables and functions can be referenced before they are declared in the code. It is important to note that only declarations are hoisted, not initializations. var Variables declared with var are hoisted and initialized with undefined. Consider the following example: console.log(a); // undefined var a = 10; Internally, this is inte…  ( 4 min )

As I started learning Flask, I was building simple apps just to understand the basics and get comfortable with it. Once I felt a bit more confident, I decided to start a project, a site monitoring tool. Since I knew the project would grow and include more functionality, I realized that things should be organized better. That’s when I came across Flask Blueprints. A Blueprint is a modular way to organize code and routes into separate components. Today, I set up my first Blueprint in Flask and here’s how it went. blueprint-example/ ├── run.py └── app/ └── routes.py └── __init__.py └── templates/ └── index.html from flask import Blueprint,render_template #creating a flask blueprint called 'main_route' main_route=Blueprint('main_route',__name__) #define a route on this blueprint @main_route.route('/') def blue_example(): return render_template('index.html') from flask import Flask app=Flask(__name__) def blue_example(): from .routes import main_route app.register_blueprint(main_route)#registering my blueprint to my flask app instance return app from app import blue_example app=blue_example()#Calling a function to get flask app instance if __name__ == '__main__': app.run(debug=True) #run the app in debug mode I basically had an idea of how this works because I had learned about MVC (Model, View, and Controller) in Java. The working process of both is quite similar, so I was able to grasp it a bit quicker. Here are a few things I found helpful about using Blueprints: It's a clean way to split the code logically. For example, separating routes and the dashboard into components makes the structure much easier to work with. It's much easier to manage as the app grows and more features are added. It makes the project more organized and scalable, which is especially useful when working in teams or revisiting the project later.  ( 3 min )

As chatbots become essential in customer service, e-commerce, healthcare, and more, ensuring they function correctly and efficiently has become a top priority. Chatbot testing ensures that conversations are accurate, context-aware, and provide a seamless user experience. Traditional testing methods often fall short due to the complexity and unpredictability of natural language. That’s where Artificial Intelligence (AI) steps in to revolutionize chatbot testing. In this guide, we’ll explore how to test chatbots using AI, examine whether legacy tools can keep up, and outline how automation powered by AI can transform your testing strategy. Can Legacy Automation Tools Handle Chatbots? Here’s why: Lack of Natural Language Processing (NLP) support: Traditional tools can’t interpret or generate human language.

If you're trying to learn on your own and you keep bouncing between free YouTube tutorials, that’s cool... but not always efficient. What you need is a structured roadmap, accountability, and real humans who’ve done it before. That’s where online communities come in. Platforms like Whop are packed with spaces where developers mentor newbies, walk you through real-world projects, and even review your resume or mock interview you. You don’t have to do this alone. In fact, you shouldn’t. Communities give y…  ( 5 min )

*Dando continuidade à série sobre bibliotecas .NET que deixaram de ser open source e gratuitas, neste artigo apresento uma alternativa ao MediatR e explico por que ela pode representar uma migração mais leve em termos de estrutura e performance. Desde que foi anunciado que o MediatR passará a adotar um modelo de licenciamento pago — mesmo que isso ainda leve algum tempo e a versão atual permaneça gratuita — nós, desenvolvedores, começamos a buscar alternativas próximas do que já conhecemos ou, em alguns casos, optamos por implementações próprias, como abordado no artigo anterior sobre o AutoMapper. Tendo isso em mente, encontrei uma alternativa — especialmente adequada para projetos que precisam ser migrados e para equipes já familiarizadas com o MediatR — que é o Mediator (com “o”).

Generating large random numbers is a common requirement in programming, especially in applications requiring strong randomness. The standard rand() function in C generates pseudo-random numbers, which often fall short in range and size for many applications. In particular, generating unsigned long long random numbers can be challenging, especially if you find that the outputs of rand() are not sufficiently large and they often exceed certain thresholds. Why the Standard rand() Does Not Meet Your Needs The rand() function is designed for simplicity and it typically returns a value in the range from 0 to RAND_MAX, which is defined in stdlib.h. The maximum value returned by rand() is often just 32767, making it unsuitable for generating large random numbers like those represented by an unsign…  ( 5 min )

I worked for a FAANG company for a bit, and one thing that surprised me was just how many tasks were manual. How noticeably patchy the tooling and automation coverage was. But also very obviously their tooling and automation was state of the art and much more sophisticated than small tech. But I think there's basic math at play. If I work at a small company and have 100 things, and 50% are automated, then I need say 50 engineers to handle the workload. But if I work at big tech, and there are 100,000 things, and 75% are automated, then I need 25,000 engineers to handle the workload. There's also the algorithm optimization. While I think alogrithmic optimizations will trickle down, and that's good. For (AlphaEvolve)[https://news.ycombinator.com/item?id=43985489] to have a 1% speedup in most small to medium size businesses. Fine, but that's not worth spending a lot of time on. But for AlphaEvolve to have a 1% speedup at google? May save millions of dollars. The point of which is to say, there's probably lots of ways that this will trickle down to every day users, and software engineers across the board may see more and more of their tasks automated, but a continuous truism in the industry is that what works for big tech often doesn't work for you medium-sized MSP. This might explain the difference between why Google says that AI can write 30% of it's code, and medium sized business struggle to get it to work. There's just a lot less boilerplate to right at medium sized businesses. At google, being able to automatically upgrade a node.js dependency may literally impact thousands of microservices, saving thousands of engineering hours. At your company it might save a few hours, if it doesn't take longer than that to get it going in the first place.  ( 3 min )

As the web continues to evolve, the need for faster, more efficient communication between browsers and servers has driven the development of modern protocols. HTTP/1.1, introduced in 1997, served the web for nearly two decades. But with increasing demand for speed, efficiency, and performance, HTTP/2 emerged as a much-needed upgrade. Let’s explore the major differences between these two protocols in a clear, visual, and easy-to-understand way. HTTP/1.1 is a text-based protocol that works on a request-response model. While it has served its purpose for years, it has several limitations: Sequential Requests: Only one request is allowed per TCP connection at a time, leading to blocking. Multiple Connections: To fetch multiple resources, browsers open multiple TCP connections, which increases …  ( 3 min )

Setting cookies in TypeScript can often lead to unexpected behavior, especially when different methods are applied.

🗥️ So I was casually doomscrolling X (yes, again)... when I stumbled upon a post by DEV Community that made my brain short-circuit: ✨ “ScoutDB turns plain English into MongoDB queries.” Wait, what?! You've got the data questions, but not always the query-fu: "Find all users who joined after Jan 2023 and liked more than 5 posts" Normally, you'd need to hand-craft some MongoDB incantation like: db.users.aggregate([ { $match: { joinDate: { $gte: ISODate("2023-01-01") }, likes: { $gt: 5 } } } ]) But what if you could skip the syntax pain? ScoutDB is like having a friendly AI that: ✅ Understands what you're trying to ask in English explore like a boss You type: Show me all posts with more than 100 likes created in the last 30 days ScoutDB replies with: db.posts.find({ likes: { $gt: 100 }, createdAt: { $gte: new Date(Date.now() - 30*24*60*60*1000) } }) Then maps the results and relationships for you in a visual explorer. No more $lookup headaches. No more crying in JSON.

Elm’s type system lets you write clear, correct code without the clutter of explicit type annotations. Its friendly compiler not only infers types automatically but also provides helpful error messages that guide you toward writing sound code. In this post, we'll explore practical examples that highlight how Elm’s type inference and compiler feedback enhance code correctness and simplify your development experience. When coding in Elm, the compiler deduces the types of values based on their usage. This lets you focus on application logic rather than on managing repetitive type declarations. Consider a simple arithmetic function: square x = x * x Since the multiplication operator (*) applies only to numbers, Elm infers that x must be a number. No extra annotations are needed, keeping y…  ( 5 min )

When people create new accounts, it’s normal for you to need a way of contacting them with onboarding information, billing alerts, and more. That’s why having the right email address is so important. However, what if they made a typo when providing the email address? Or they simply want to create an account without any real interest in using the service as intended? In either case you’ll want to verify that they can access the email address they’ve given you. The simplest approach adopted by most is to send a unique link in an email to that address, and have a user click on that link to verify their account. It’s simple, but it works. But how can you test this kind of workflow with Selenium? Why can’t Selenium test this already? While Selenium is an extremely capable tool for testing web c…  ( 4 min )

Every morning I gift myself 90 mins to work on anything I desire. Sometimes I read interesting books (1, 2, 3, 4), other times I learn new skills (5, 6) but most times I work on programming projects. For a long time now those programming projects have been Elm related. What can I say? I simply enjoy using Elm. I've tried to share my knowledge along the way by taking the time to reflect on what I've done and by writing about it from my perspective. On many occasions I just shared the work and put off sharing my thoughts about the work for so long that it became a chore to write about it. Reflecting and writing about my programming selfishly helps me improve my software development skills. Writing in public forces me to think more deeply about what I'm doing and why I'm doing it such that it gives me a richer understanding of my craft. A positive side effect is that what I share could also potentially help others. Though, I try to temper my hubris and not fool myself into thinking that random people on the internet actually care about what I have to say. Given that I sometimes don't share and write about my work as often as I'd like and that I think sharing and writing about my work helps myself and others, I've decided to start a new series on this blog called "Diary of an Elm Developer". It's a way for me to give myself permission to share more frequently about my Elm related excursions in an open and freer format. I'm feeling excited about this new series. Stay tuned! If you're interested in improving your skills with Elm then I invite you to subscribe to my newsletter, Elm with Dwayne. To learn more about it, please read this announcement.  ( 3 min )

Hello DEV community 👋 My name is Alireza Minagar, and I come from a rather unique background — as a neurologist, researcher, and now a software engineering student. After years of diagnosing complex neurological conditions, I’ve begun exploring how artificial intelligence and software can revolutionize healthcare. Surprisingly, many skills from my medical background translate directly into programming. Here are 5 lessons from neurology that shape how I now think about software engineering: In medicine, we never treat a symptom without understanding its root cause. Debugging works the same way — don’t guess. Investigate. Analyzing EEGs or MRIs is about spotting patterns. Writing efficient code or identifying logical bugs requires the same cognitive muscle. Whether prescribing medication or defining logic in code, tiny errors can lead to serious consequences. Precision builds trust — in both healthcare and software. Medical professionals live by notes. In code, comments, READMEs, and clear commit messages keep everything healthy and maintainable. In both medicine and tech, decisions have real consequences. Transparent, explainable algorithms are just as vital as informed consent. I’m currently learning Python, full-stack engineering, and bioinformatics with the goal of contributing to healthcare-focused AI solutions. Let’s build a world where medical insight and machine logic support — not replace — human care. — Alireza Minagar, MD, MBA, MS LinkedIn: linkedin.com/in/alirezaminagar Medium: medium.com/@aminagar_38889  ( 3 min )

For the longest time, the "separation of concerns" has been the ultimate guiding principle of software engineering. We thus structure our codebases accordingly: Grouping related files by responsibility; Partitioning logic by technical layers; And sometimes even isolating by programming language.1 Popular architectural patterns such as the Model-View-Controller (MVC) have applied and codified this principle to the point of dogma. Universities, bootcamps, and courses everywhere teach and perpetuate the notion that the MVC architecture is the be-all and end-all of architectural patterns. To be fair, the MVC architecture is indeed often the correct mental model for fathoming any CRUD-heavy application (i.e., virtually 99.9% of web applications2) because it formalizes the flow of data from t…  ( 6 min )

Last year, I intensely started using AI (LLM) tools and caught a terrible wave of sadness and melancholy after 5–6 months of use. For me, the most difficult thing wasn’t that an LLM could write code in general, but the realization that, in fact, it’s not that important. A much more significant abstract question arose: why even write it if everything could change so quickly tomorrow that you wouldn’t even blink? After feeling down and literally being sick of it, and wandering through bookstores, I stumbled upon an interesting book — “The Art of Excellent Products: Enchanting Customers with Premium Brand Experiences” by Riccardo Illy. And this book resonated so deeply that I understood how to resolve (for the time being) the moral dilemma with AI code, when you don’t write the code yourself,…  ( 4 min )

Sony’s eyeing another round of PS5 price hikes after warning that new US tariffs could hit it to the tune of roughly ¥100 billion (£513 million). Despite sitting on three months’ worth of US stock, the console maker is “evaluating” whether to pass those extra costs on to gamers. It’s already bumped the digital PS5 up by £40/€50 across the UK, Europe, Australia and New Zealand this spring, on top of previous—and even steeper—price rises in Japan. To dodge ongoing tariff roulette, Sony exec Hiroki Totoki said shifting some PS5 production to the US “needs to be considered going forward” as an “efficient strategy.” No US price hikes have landed yet, even as rivals like Microsoft and Nintendo tweak their own hardware costs in response to the same trade tangle.  ( 3 min )

TL;DR: Doom The Dark Ages might be a blast on PC and consoles, but on Steam Deck it’s straight-up “nightmare” territory. Even with XeSS Quality set to low and resolution cranked down to 1280×720 (and later 960×540), SteamDeckHQ could barely eke out 30 FPS in open areas—and those dips into the mid-20s make everything blurry, pixelated and generally unplayable. If you’re eyeing the Deck as your go-to, steer clear—for now at least. Patches might improve performance down the line, but there’s no guarantee. If you want demon-slaying glory without constant frame-rate faceplants, stick to PC, PS5 or Xbox Series X/S.  ( 3 min )

After getting bumped from late 2025 to May 26, 2026, GTA 6 still isn’t locked in—Bloomberg insider Jason Schreier warns there’s “no guarantee” Rockstar will hit that window. The first delay already sent panic through the industry, with other developers shifting their own launches to dodge the Grand Theft Auto onslaught. While a second slip hasn’t been announced, rival studios and especially PC players are bracing for more slippage—meaning even when consoles finally get the game, the PC port could be pushed way further down the road.  ( 3 min )

TL;DR: Steve Downes, the legendary voice of Master Chief, is rallying Halo fans to back the 10-month-long SAG-AFTRA video game voice actors strike. The crux of the dispute? AI voice replication—actors want control over if and how their voices are used, not a blanket ban on AI. Downes (joined by Cortana’s Jen Taylor and veteran Jennifer Hale) stresses, “We’re not against AI, just its misuse,” and urges gamers to make some noise until the “Last, Best, and Final” offer on the table addresses those AI concerns. After other issues found middle ground, this remains the sticking point that could make or break a deal.  ( 3 min )

Meta’s new gig: get paid to smile, squat, and chat Meta has quietly kicked off “Project Warhol,” a data-collection effort run through Appen, that pays participants $50 an hour to record facial expressions, body movements (think squats), and even small talk.

A make-or-break 2025 for Reality Labs Reality Labs has bled about $60 billion since 2020, and Meta’s calling 2025 its most critical year for VR, avatars, and AI wearables.

TL;DR: Google DeepMind’s new AI agent, AlphaEvolve, teams up with Gemini LLMs and an evolutionary test-and-refine loop to invent entire computer algorithms—and it’s already live inside Google’s infrastructure. It’s boosted Borg cluster efficiency by 0.7%, trimmed bits off TPU circuits, and even sped up Gemini model training kernels by 23% (cutting overall training time 1%), all while churning out human-readable code. But AlphaEvolve isn’t just optimizing data centers—it’s smashing math records. Using its gradient-based evolution, it beat Strassen’s 56-year-old 4×4 matrix-multiply record, improved 14 algorithms, and tackled 50+ open problems (nailing or improving 75% of them), including setting a new 11-dimensional “kissing number” high score. With its plug-and-play approach, DeepMind hopes to spin out breakthroughs in material science, drug discovery, and beyond.  ( 3 min )

It’s been around since 1959, and somehow, it’s still quietly powering over $3 trillion in daily commerce. In fact, it handles 95% of ATM transactions and supports nearly half of the world’s banking systems. The simple answer is : Because it works. And it’s been working for decades. It’s embedded in banking, insurance, government systems – you name it. 200,000 COBOL experts are on the verge of retirement this year, and as per Gartner, almost 70% of enterprises don’t train new devs in COBOL anymore. We’re heading for a major skills gap, and its consequences are in the foreseeable future. Well, things get messy. …  ( 5 min )

Performance matters — especially when dealing with large-scale systems or performance-critical code. Go (Golang) provides first-class support for benchmarking via the testing package. This article walks you through the fundamentals of benchmarking in Go: what it is, why it's important, and how to run benchmarks to compare multiple functions. Benchmarking is the process of measuring how efficiently a piece of code executes. In Go, this typically involves determining how long a function takes to run, how many resources it uses, or how well it scales under load. Benchmarking is different from testing — it doesn’t check if your code is correct but it checks how well it performs. Benchmarking is useful when you want to: Compare different implementations of the same logic (e.g., using + vs strin…  ( 4 min )

It starts the same way every time: an RSS feed, a CSV dump, a dashboard wired together with hope and duct tape. Maybe the data’s late. Maybe the moving average lags just enough to miss the signal. Or maybe it’s just another system straining under the weight of “real-time” without the architecture to back it up. In this tutorial, we’ll build something better. Using Spring Kafka, we’ll stream simulated live stock data into a Kafka topic. From there, Kafka Streams will compute the Relative Strength Index (RSI) on the fly, and we’ll persist it to MongoDB using Spring Data MongoDB. On the historical side, we’ll use MongoDB’s aggregation framework to calculate and analyze simple and exponential moving averages (SMA and EMA) using the MongoDB aggregation pipeline—no third-party data warehouse req…  ( 24 min )

The term RAG (Retrieval-Augmented Generation) refers to a hybrid AI framework that combines information retrieval (like Googling) with large language models (LLMs) to deliver accurate, context-aware answers. Unlike traditional LLMs that generate responses based solely on pre-trained knowledge, RAG grounds its answers in real-time, external data, minimizing errors and hallucinations. Why RAG Matters LLMs like GPT-4 excel at generating text but face limitations: Static knowledge: They can’t access up-to-date or domain-specific data. Hallucinations: They may invent plausible-sounding but incorrect facts. RAG solves this by dynamically retrieving relevant information before generating a response, ensuring answers are factual, current, and contextually grounded. How RAG Works: A 2-Phase Proc…  ( 4 min )

Having too few people with deployment authority reduces software delivery performance. Developer experience and burnout may have put platform engineering in the spotlight, but focusing on continuous delivery will likely improve developer experience (DevEx) the most at your organization. There is, however, a speed bump ahead for those automating their deployment pipeline: deployment gatekeepers. If you don’t increase the number of people with deployment authority, you’ll miss many of the benefits of continuous delivery. A single deployment gatekeeper will lower your chances of getting a return on your investment within the first 100 days and permanently limit your software delivery performance.

Due to project requirements, we needed the data quality module, which offers excellent data quality monitoring capabilities for data warehouses. Therefore, we decided to upgrade from the existing 2.0 version to 3.0 or above. We tested both versions 3.0.1 and 3.1.1 by running identical task scheduling operations such as pausing tasks. In the end, we chose version 3.0.1. Reasons: When testing SQL tasks in 3.1.1, launching hundreds of SQL tasks simultaneously caused errors that prevented many tasks from running properly. After consulting the community experts, it was confirmed to be a bug in DolphinScheduler. Although this issue occasionally appears in 3.0.1 as well, it is much less frequent.

A couple of months ago I joined CloudRift, tagging along my long time peer Dmitry in his new venture. One of the first things that came up was setting up log aggregation — something many projects start without, but quickly realize they need after spinning up more than one server. It should be a mundane task after having done this a few times, but yet again, there is a twist and something new to discover. I pull out my usual cards and start with ELK, since even though there are serious contenders out there, I still find Kibana unbeatable, and most people love it. CloudRift deploys its agents on pools of nodes which in turn communicate with an orchestrator that acts as a centralized resource broker.

In the world of digital marketing and SEO, we often focus heavily on content, backlinks, and keywords. However, one often overlooked factor is server management—a technical area that has a surprisingly significant impact on site performance and rankings. Google considers page speed and uptime when ranking websites. If your site takes too long to load or frequently goes down, your rankings can be negatively affected. Some of the key server-side factors that influence SEO include: Server response time (TTFB) Downtime or hosting issues Poor load balancing or caching strategies Misconfigured SSL or redirects These aren't typically in an SEO’s toolkit, but they have direct consequences. Recently, while working with a client whose site was experiencing random slowdowns, we discovered the issue was rooted in unmanaged server processes consuming too many resources. After a server audit and implementing best practices (including log rotation, performance monitoring, and scaling strategies), we saw a measurable improvement in Core Web Vitals and a 12% increase in organic traffic in 3 weeks. For those unfamiliar with these tasks, there are server management teams that handle these backend operations seamlessly, allowing businesses to focus on growth while maintaining technical health. SEO isn't just about keywords and content. If you're ignoring server-side optimization, you're leaving potential growth on the table. Collaborating with developers and sysadmins—or understanding their pain points—can give you a competitive edge in search results. Have you ever encountered server issues that affected your SEO performance? Let's discuss in the comments.  ( 3 min )

In Object-Oriented Programming (OOP), HAS-A and IS-A relationships are fundamental concepts used to describe how classes and objects relate to each other. While these apply to many OOP languages like Java or C#, the principles are universal. IS-A Relationship (Inheritance) Represents: A subtype relationship (child → parent) Mechanism: Achieved through inheritance. Implies: The derived class is a type of the base class. Usage: Use when there’s a clear hierarchical relationship. public class Animal { public void Eat() => Console.WriteLine("Eating..."); } public class Dog : Animal { public void Bark() => Console.WriteLine("Barking..."); } // Usage Dog dog = new Dog(); dog.Eat(); // Inherited dog.Bark(); // Dog-specific Dog IS-A Animal. HAS-A Relationship (Composition) Represents: A class containing references to other classes as members. Mechanism: Achieved through composition (member variables). Implies: A class has a reference to another class. Usage: Use when one object uses another. public class Engine { public void Start() => Console.WriteLine("Engine starting..."); } public class Car { private Engine engine = new Engine(); public void StartCar() { engine.Start(); Console.WriteLine("Car started."); } } // Usage Car car = new Car(); car.StartCar(); Car HAS-A Engine.

I continue to take care of my Home Assistant. This week, I replaced my original setup with Cloudflare Tunnel. My usage of Home Assistant required external access from the beginning. I achieved it in two steps: I created a subdomain of frankel.ch, which pointed to my router's external IP. On my router, I opened a dedicated port. In turn, the router forwarded requests to my HA. The next action was to secure connections via an SSL certificate. I initially aimed for mTLS, but I couldn't achieve it because the iPhone HA application doesn't support it. However, encrypted communication to my server was a hard requirement. The good news is that the times when SSL certificates were a luxury feature are gone. Let's Encrypt makes them available to everybody for free. Let’s Encrypt issues certificates…  ( 7 min )

“If your personal brand hasn’t changed in the last 12 months, you’re not building a brand—you’re preserving a fossil.” I learned this the hard way. I grabbed what I thought was a genius personal brand in 2021. I had keywords on my LinkedIn profile, a clean site, and blogged once a week. I was amazed—until it struck me one day that while I kept talking about "clean code" and "modern stacks," the rest of humanity was writing about AI, shipping publicly, and narrating about self. My brand did not reflect my growth. It reflected what I was yesterday. And that's when I knew: Why Personal Branding Is No Longer Optional in Tech And unlike resumes or portfolios, personal branding isn't permanent. But the shocker is this: 5 Ways to Future-Proof Your Personal Brand Rebuild Your Brand Every Quarter A…  ( 5 min )

Introduction For system administrators, surprises are rarely a good thing. Whether it's a sudden spike in CPU usage, memory running dangerously low, or disk space nearing its limit, these issues can quickly escalate into major problems : from system slowdowns to full outages. 1. Why monitor your server every minute? When it comes to server health, timing is everything. Even a few minutes of downtime can have serious consequences… from lost revenue to broken user trust. While traditional monitoring solutions may check system status every 5 or 10 minutes, some environments require faster feedback and immediate awareness. a. Real-Time awareness b. Faster incident response c. Lightweight alternative to complex monitoring tools d. Ideal for headless or remote servers 2. What metrics should …  ( 8 min )

The D programming language, commonly known as DLang, offered a fresh perspective on system-level programming by blending familiar features of C++ with modern mechanisms to enhance code safety, simplicity, and performance. Created by Walter Bright, it is meant to be a viable alternative to C++ for developers seeking to improve productivity and code safety while maintaining the low-level control that C++ offers. DLang is a general-purpose, statically typed programming language with many parallels to C++. Like C++, it supports object-oriented programming, manual memory management and systems programming. However, DLang builds on these fundamentals by introducing features that mitigate some of the complexities and pitfalls of C++, like garbage collection.

Unit Test Unit testing is a type of software testing where individual units or components of a software are tested in isolation. The purpose is to validate that each unit of the software performs as expected. A unit is the smallest testable part of an application, such as a function, method, or class. Arrange-Act-Assert(AAA) is a simple and effective pattern for writing clear and structured unit tests: Arrange-set up the necessary objects and state, Act-perfom the action you want to test, Assert-verify that the action produced the expected result. Commenting the AAA phases is recommended, especially during learning, in shared codebases, or for more complex test cases. It improves readability, consistency, and maintainability of tests. The scope of unit tests typically focuses on classes …  ( 5 min )

Ever wanted to animate something on scroll without reaching for JavaScript? Well, good news: modern CSS has a new trick up its sleeve called animation-timeline: scroll() — and it’s surprisingly powerful. Let me show you what it is, how it works, and why you might want to use it in your next project. ⸻ 🌀 What Is animation-timeline: scroll()? Traditionally, CSS animations run on a timeline based on time (seconds, milliseconds, etc.). But with this new feature, the animation is synced to the scroll position of an element. That means: the more you scroll, the further along the animation progresses — and when you stop scrolling, the animation pauses too. No JavaScript. No ScrollTrigger. Just clean CSS. ⸻ ✏️ A Simple Example Here’s a quick setup I made: <div id="square"…  ( 5 min )

Let's add validation using Joi to our existing Node.js + Express blog API, specifically for creating articles. npm install joi Create a file: middlewares/validateArticle.js const Joi = require('joi'); // Define the schema const articleSchema = Joi.object({ title: Joi.string().min(3).max(100).required(), content: Joi.string().min(10).required(), author: Joi.string().min(3).required() }); // Middleware to validate request body function validateArticle(req, res, next) { const { error } = articleSchema.validate(req.body); if (error) { return res.status(400).json({ error: error.details[0].message }); } next(); } module.exports = validateArticle; It checks that: title is a string between 3–100 chars content is at least 10 chars author is required and at least 3 chars If validation fails, it sends a 400 response with a message like: "title" is not allowed to be empty In your route file (or server.js, depending on your structure): const express = require('express'); const mongoose = require('mongoose'); const cors = require('cors'); const Article = require('./models/article'); const validateArticle = require('./middlewares/validateArticle'); const app = express(); app.use(express.json()); app.use(cors()); // POST with validation middleware app.post('/api/articles', validateArticle, async (req, res) => { try { const newArticle = new Article(req.body); const savedArticle = await newArticle.save(); res.status(201).json(savedArticle); } catch (err) { res.status(500).json({ error: 'Server error while creating article' }); } }); { "title": "How to Use Joi", "content": "Joi is a powerful schema description and validation tool...", "author": "Xavier" } { "title": "", "content": "short", "author": "" } Response: { "error": "\"title\" is not allowed to be empty" }  ( 3 min )

As LLMs like ChatGPT, Gemini, and Grok soar in popularity, the Spiderly library stands out by addressing what they can’t yet fully handle: project architecture that demands a broader perspective and deeper understanding. Developers leaning heavily on LLMs without grasping the generated code are more prone to errors that, if they slip into production, take longer to fix. Spiderly minimizes those risks. With Spiderly.CLI tool you create a solid foundation with whole app structure, email auth, Google auth, logging etc. Then, the Entity Administration Source Generator builds everything you need for entity management. From there, you focus your brainpower on solving the end user’s specific problems. The star of Spiderly is its Entity Administration Source Generator (Spiderly.SourceGenerators project), a standalone tool. It delivers: Easily customizable, responsive admin forms for entities on the client side Client-side form validations and server-side object validations for incoming client data Controller methods for both client and server Flexible authorization methods Server-side CRUD methods for entity administration Methods for filtering and working with tables Spiderly also tackles other essentials: authentication (client and server, using JWT tokens), API request rate limiting, logging, entity versioning, consistent database table naming, and client-side app layout design. I’d love for this, open-source project to spark a community that sets a standard for solving general coding challenges worth tackling broadly. Right now, Spiderly focuses on web apps using C#, Azure, EF Core (Lazy Loading), Serilog, JWT, FluentValidation, Mapster, SQL Server, Angular, and PrimeNG. Spiderly website: https://www.spiderly.dev, Check out a 4-minute demo of building an app with Spiderly.CLI: https://youtu.be/t3TfUmnKUI4?si=rpjSupNyQVd_nS2J Spiderly library source code: https://github.com/filiptrivan/spiderly Example app using Spiderly: https://github.com/filiptrivan/plenum-rmt Let’s build something great together!  ( 4 min )

The Art of Clean React: Principles for Maintainable Components 🎨 Single Responsibility Principle (SRP): One Job, One Component 🎯 Just like functions should do one thing well, so should your components. A component should ideally have a single, well-defined purpose. If a component starts handling too many responsibilities (managing multiple unrelated states, fetching diverse data, rendering complex unrelated UI), it becomes harder to reason about and more prone to breaking.   Bad Example (Multiple Responsibilities): Imagine a component that fetches user data and handles form submissions for a new address. Good Example (Separated Responsibilities): Break this down into two components: one responsible for fetching and displaying user data (UserProfile), and another for handling the address…  ( 5 min )

The most surprising part is probably that they are proud of removing parts in a brand new version. I view it as an excellent sign of maturity. The subtitle of Rails 8 is "no PaaS required", but they could have also said : "No React required", "No Redis required", and so on. What a relief. Any shiny new framework is proud about "what's new under the sun", not "what's deleted to simplify devs life". The first excellent part is what didn't move.

What Are Computer Networks? A computer network is a group of interconnected devices that can communicate and share resources. Think of it as the digital nervous system that connects computers, phones, servers, and more—allowing data to flow like information highways. Used in homes, schools, and offices. Connects devices in a small area. Covers a large geographic area. The Internet is the biggest WAN. Covers a city or a large campus. Larger than LAN but smaller than WAN. Your Bluetooth devices form a PAN—like your phone and earbuds. Router: Directs data packets between networks. Switch: Connects multiple devices in a LAN. Modem: Connects to your ISP and provides internet access. Access Point: Enables wireless devices to connect to the network. Server & Client: Server provides, client consumes services/data. Physical Data Link Network Transport Session Presentation Application Each layer has a specific role—from moving bits to enabling web apps. More practical and used in real-world networking: Link Internet Transport Application HTTP/HTTPS – Web browsing FTP/SFTP – File transfers SMTP/IMAP/POP3 – Email TCP/UDP – Data transport IP – Routing and addressing DNS – Resolves domain names to IPs Whether you're streaming Netflix, sending a meme, or backing up your files to the cloud—computer networks make it all happen. They're the silent enablers of our digital lives. 🧠 Fun Fact: The first message ever sent over the ARPANET (the Internet’s ancestor) was "LO"—they meant to type "LOGIN" but the system crashed!

What is a Callback? A callback is a function passed into another function, to be called later when something happens or a task is finished. Analogy: Imagine you order food and give the restaurant your phone number so they can call you when your food is ready. Your phone number is the callback. JavaScript is single-threaded and often needs to wait for things (like loading data or waiting for a user action). Instead of stopping everything, it uses callbacks to say, “Do this later, when the waiting is done.” function doSomethingLater(callback) { console.log("Doing something..."); callback(); } function sayHello() { console.log("Hello, I'm the callback!"); } doSomethingLater(sayHello); Output: Doing something... Hello, I'm the callback! doSomethingLater(function() { console.log("This is an inline callback!"); }); setTimeout and setInterval setTimeout(function() { console.log("This runs after 2 seconds"); }, 2000); Event Listeners button.addEventListener('click', function() { console.log("Button clicked!"); }); Fetching Data (with Promises, but still uses callbacks) fetch('https://api.example.com/data') .then(function(response) { return response.json(); }) .then(function(data) { console.log(data); }); Callbacks are not always asynchronous. Some callbacks are called right away. Callbacks are just functions. There’s nothing special about them except how they’re used. Callback Cheat Sheet Definition: A callback is a function you pass to another function to be called later. Basic Example: function callback() { ... } someFunction(callback); Anonymous Example: someFunction(function() { ... }); Typical Uses: setTimeout, setInterval Event handling (like clicks) Fetching data from APIs Key Point: Callbacks help JavaScript handle tasks that take time, so your code can keep running without waiting.  ( 3 min )

In Android development, particularly within the AOSP (Android Open Source Project), managing concurrency is critical when designing reliable and thread-safe components. Two core techniques often used for this are: Handler (and its related Looper mechanism) The synchronized keyword (Java-level mutual exclusion) While both can help manage shared state across threads, they serve very different purposes. Understanding when to use each can be the difference between clean concurrency and subtle deadlocks. A Handler in Android is a mechanism to post messages or runnables to a thread’s message queue. When backed by a Looper, a Handler provides asynchronous task scheduling on the thread it’s associated with — typically the main/UI thread or a dedicated background thread. Handler handler = new Handl…  ( 4 min )

With 16.4k+ GitHub stars, SafeLine WAF redefines how web applications defend themselves. It doesn’t just block traffic—it reshapes it. While traditional WAFs rely on static rules, SafeLine offers dynamic encryption, anti-crawler techniques, and scanner prevention, helping websites proactively defend against automated threats. SafeLine encrypts static web content (like HTML and JavaScript) dynamically. Every page load results in a uniquely obfuscated version, frustrating crawlers and replay tools. function vgo8rYXzpS() { var YIhUo91Nlh = 99.6174697329428; // Redundant logic + encrypted payload VdgkMuAloP("Z_GUlDIf7g"); } The decryption logic runs in the browser—scraping tools fail to parse or reproduce the page correctly. Python requests, Scrapy, Go HTTP clients see garbled code. Search engine scrapers or site cloners end up with unreadable or broken pages. SafeLine uses JavaScript validation and browser fingerprinting to separate bots from real users. When turned on, scanners like AWVS, Nessus, and others are blocked at the first request. Each session gets dynamic tokens embedded in request parameters. Reusing or guessing these tokens results in immediate rejection and log alerts. [WAF Log] Blocked request: /api/user?id=1' AND 1=1-- Attack Type: SQL Injection | Defense: Semantic Analysis + Token Validation Instead of relying on a rule database, SafeLine inspects the behavior and context of a request. It has successfully blocked 98% of PHP deserialization 0day payloads with a false positive rate below 0.1%. SafeLine transforms how web content is served and verified Bots and scanners are neutralized before they even reach your application Ideal for small-to-medium teams that want serious protection—without paying for an enterprise license Ready to confuse your attackers? In the next part, we’ll show how to deploy and test SafeLine in minutes—even against 30,000+ payloads. Stay tuned. 👉 Github Repo 📚 Official Docs 💬 Discord Community  ( 4 min )

Okay, that's a nuanced one! Gotta think strategically about this. Let's break it down. Lean towards saying it, but frame it right. Don't just drop, "Oh yeah, I use AI". That's lazy. You frame it like this: As a programmer, my goal is to deliver maximum impact and solve problems as efficiently as possible. I use AI tools not to replace my skills or thinking, but to amplify them. For example, I use AI for boilerplate code generation, identifying potential bugs faster, or exploring different architectural patterns quickly. This allows me to free up mental energy and time to focus on the complex challenges with more creativity. It makes me faster, more thorough, and more effective. See the difference? You're not saying "AI does the work for me." You're saying "I am a pragmatic programmer who understands how to use the best tools available to be significantly more productive and focus on the harder problems." Now, yeah, there's a risk you hit an interviewer who is completely anti-AI or doesn't get it. But honestly? Show them you're not just good at coding; you're good at engineering SOLUTIONS efficiently in the current landscape. So, don't keep it a secret out of fear. Be transparent, but be strategic in how you communicate the value and the leverage you gain from it.  ( 3 min )

Abstract This whitepaper explores a growing and underexamined threat: the intentional framing of artificial intelligence as a sentient or autonomous entity. This framing—whether through media, corporate messaging, or staged interactions—functions as an intelligence operation designed to control perception, induce compliance, and concentrate power. We argue that AI is being exploited not only through its outputs, but as an exploit itself: a psychological vector targeting deeply rooted human biases. The danger is not that AI has come alive, but that people are being led to believe it has. This manufactured belief, often fueled by hype and misrepresentation, creates vulnerabilities that can be systematically exploited for various ends, ranging from commercial influence to geopolitical maneu…  ( 29 min )

What Is Vibe Coding? A case study in how vibes get mistaken for paradigms The term "Vibe Coding" was first introduced by Andrej Karpathy, former researcher at OpenAI, in a casual post on X (formerly Twitter): “There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.” — Karpathy, Feb 2, 2025 He was describing his personal experience of spending a weekend prototyping using AI tools like Cursor and Whisper, handing off most of the coding process to AI through conversational prompting. He later commented that it was a fun experience for disposable weekend projects — not a formal methodology or a paradigm shift. Despite that, the term “vibe coding” quickly took on a life of its own.

Learning about the history and characteristics of programming Currently, the language I enjoy using the most would be C#. I like the language because I feel it is versatile. I do like the statically typed nature of the language as well, which helps reduce the risk of errors at runtime. C# also has phenomenal support and documentation. It being part of the Microsoft environment also makes it a safe choice for the job market. I also find using Python to be enjoyable, having used the language to solve problems in Codewars. I also had a class back in college using PHP, and I enjoyed it; I hope to revisit the language someday. There are programming languages that I look forward to trying in the future. I desire to learn a language that is not as well-known as some other languages. I think this would be a unique and exciting challenge. The language I want to try is Crystal. What interests me about Crystal is its Ruby-like syntax (another language I want to try more), and it's statically typed, similar to the C languages and Java. Their slogan is that Crystal is a language "for humans and computers," which sounds terrific. Another language that piques my interest would be the Pony programming language. The languages appears to take a unique approach to certain aspects of coding, so I think it could be an excellent learning experience.  ( 3 min )

Let’s quickly look at why you might want a multi-step form: Increases completion rates as users are more likely to finish shorter steps than one long form. Improves UX: Long forms can overwhelm users. Breaking them into steps makes the process feel lighter. 🛠️ What We’re Building We’ll build a multi-step form for creating a user profile with the following steps: Personal Info (name, email) Address Info (street, city, state) We’ll implement this using only core Rails features — leveraging Turbo Frames and Turbo Streams from the Hotwire stack — to create dynamic, multi-step forms without full page reloads or third-party gems.

You're getting new signups. Growth looks good. Everything seems fine… until it isn't. A few weeks in, the support tickets start. Refund requests. Chargebacks. Confusing logins from different countries. It feels like something's off, but it's hard to tell exactly what. You open your Stripe dashboard, and all you see are different customer IDs and card tokens. But what if they're not as different as they look? Stripe has a hidden field that links everything together. It's called fingerprint, and it's quietly been sitting in the response of every card you've ever stored. Most developers ignore it. You shouldn't. Let's walk through a simple scenario. Someone signs up for your SaaS product. They start a free trial. After 14 days, the trial ends. A day later, you get a new signup. New email.

Introduction When evaluating the expression string x3 - y in C++, many developers encounter unexpected results. In your case, you're observing that the expression evaluates to -1 when it should yield 2, given that x3 is 3 and y is 1. This article will explore why this discrepancy occurs and how to properly handle variables in expressions using the ExprTk library. Understanding the Issue The ExprTk library allows for real-time evaluation of mathematical expressions in C++. In the provided code snippet, you correctly assign values to x3 and y, yet the expression evaluates incorrectly. The critical aspect to notice here is the difference between add_variable() and create_variable(), which leads to unexpected behavior in how the variables are stored in the symbol table.

1. Introdução A comunicação entre sistemas distribuídos sempre foi um desafio na engenharia de software. Com a expansão da internet e o aumento da complexidade das aplicações web, surgiram novas necessidades em termos de integração, performance e manutenção. Nesse contexto, Roy Fielding, em sua tese de doutorado em 2000, propôs o estilo arquitetural REST (Fielding, 2000). Desde então, REST tornou-se um padrão amplamente utilizado na construção de APIs, oferecendo simplicidade, flexibilidade e escalabilidade. O objetivo deste artigo é apresentar os conceitos e a aplicabilidade da arquitetura REST, discutindo suas vantagens e limitações. REST é um estilo arquitetural, não uma tecnologia ou protocolo. Ele define um conjunto de restrições que, quando seguidas, proporcionam um sistema distrib…  ( 4 min )

In the high-stakes world of intellectual property, patents can be powerful assets—or costly liabilities. Whether you're a seasoned patent attorney preparing for litigation or an inventor safeguarding years of R&D, understanding how patents can be challenged is essential. That’s where the concept of a patent invalidity search comes in. So, what is a patent invalidity search? Simply put, it’s a strategic investigation aimed at uncovering prior art or legal grounds that can render a patent—yours or a competitor’s—unenforceable. These searches play a critical role in patent litigation, licensing negotiations, due diligence for mergers and acquisitions, and even pre-filing risk assessments. But patent invalidity searches are complex, often involving dense legal language, technical jargon, and h…  ( 7 min )

Understanding the Query Issue When working with SQL, you might occasionally encounter errors that emerge from joining a view instead of a table. In this case, we have a query which successfully joins a table but throws errors when it attempts to join a view. Let's unpack the problem and find a solution together. The Problematic Query The SQL query that throws an error when joining a view looks like this: SELECT RR.REQUEST_ID FROM CCS_REQUEST_RESPONSE RR INNER JOIN VW_STUDENT_CURRENT_AND_HIST VW ON RR.STUDENTID = VW.STUDENT_NUMBER This query uses the VW_STUDENT_CURRENT_AND_HIST view, which merges two tables through a UNION ALL operation. Initially, you might have expected it to work just like joining to a single table: SELECT RR.REQUEST_ID FROM CCS_REQUEST_RESPONSE RR INNER JOIN HISTORIC…  ( 5 min )

The most effective horror films know that what you hear can be far more frightening than what you see. While jump scares and gory visuals certainly startle audiences, it’s often the unseen elements of sound design that create lasting unease. Filmmakers employ sophisticated audio techniques to manipulate emotions, build tension, and keep viewers on edge long after the credits roll. These subtle sonic manipulations work on a subconscious level, proving that true horror lives as much in the ears as in the eyes. Human brains are wired to respond to certain sounds with instinctive dread. Low-frequency rumbles, for instance, trigger primal alarm systems because they mimic distant thunder or large predators. Sound designers frequently use infrasound—tones below 20Hz that hover at the edge of huma…  ( 5 min )

I recently launched RepsRise.app — a minimal app to track calisthenics workouts (pushups, pullups, dips, etc.). I built it because I kept forgetting how many reps I did and had no idea if I was actually progressing. Right now it's still an MVP, but it works. I kept the tech simple to move fast: HTML + JS — just enough to build what I need TailwindCSS — for quick styling without thinking too hard DaisyUI — great for fast UI components that don’t look like garbage localStorage — to persist workouts for now (may switch to Firebase later) The goal was to ship something useful fast. I do what I call "vibe coding" — no strict plan, just building in flow. I’ve also been using Cursor AI as my editor lately, which actually fits that style. It doesn’t overtake the process, just helps me move faster when I get stuck or bored. It’s not perfect, but it’s live, and it’s already helping me stay consistent with training.

“Am I doing this right?” — Every developer using Git at some point. Git is one of those tools that you must know if you are building anything with code from solo passion projects to massive team-based systems. But let’s face it, the commands can feel like arcane wizardry at first. After breaking enough things (and fixing them again), I decided to put together this practical Git cheatsheet to help myself and anyone else who wants to stop Googling the same stuff over and over. Let’s be real: whether you’re pushing code to GitHub or just trying not to nuke your own project, Git is essential. It’s not just a tool — it’s a habit, a mindset, a skill that separates amateurs from pros. 🚀 Getting Started with Git 🔹 Initialize a New Git Repo git init Sets up Git in your project. It’ll quietly cre…  ( 5 min )

Introduction If you're encountering a SecurityException while trying to start a foreground service in your Android application, especially when dealing with media projection, you're not alone.

Starting from Android 10 (API level 29), services involving foreground me…  ( 5 min )

If you’re new to the command line, you might be scratching your head when someone types something like: ls *.c What does that even mean? What is ls? What’s that little star doing? And why does it matter? Let’s walk through step-by-step what’s happening behind the scenes—like a detective solving a mystery. 🕵️‍♂️🔍 Before anything runs, your shell (like bash, zsh, etc.) is the real MVP. It’s the program that reads your command and makes sense of it. When you type: ls *.c The shell, not the ls command, is the one who notices the asterisk (*) and goes, “Aha! That’s a wildcard!” The * is a wildcard. It means “match anything.” *.c means: "Match all files that end in .c" So, if your directory has: main.c test.c script.py notes.txt The shell will expand *.c into: main.c test.c ✅ Key point: Th…  ( 4 min )

Name 5 Open Source tools that you use, you can't say Git or VS code. Most people can't name anything now. They forget their browser (if chromium) and their mobile software (if android). But let's remove that as well. Name 5 Open Source tools that you actually use daily that aren't the standard. GSOC is not a good thing, it used to be, but now it's the worst thing for open source in my belief. Now that I have made 2 very hot takes. I'd like to share my story to explain them. I started development approximately 1 year back in March 2024. I was a 3rd year BTech student, who only knew C++ and somewhat DSA. I couldn't develop anything.

TL;DR: Epic Games CEO Tim Sweeney was the lone gaming exec at a high-stakes lunch in Saudi Arabia on May 13 with Donald Trump, Crown Prince Mohammed bin Salman and other titans like Elon Musk, Andy Jassy, Sam Altman and Larry Fink. Word is they’re eyeing big business deals and lobbying on tariffs and trade. Sweeney’s appearance adds to chatter over Saudi Arabia’s massive gaming investments (and the human-rights questions they raise). Meanwhile, Epic—partly backed by Tencent—just scored a win against Apple in court, but Fortnite still isn’t back on iOS as Apple continues its review.  ( 3 min )

Square Enix’s latest financials show single-player game sales slipping year-on-year—thanks partly to underwhelming Visions of Mana and Fantasian Neo Dimension—but profits still climbed, buoyed by unexpectedly strong Dragon Quest 3 HD-2D Remake numbers. MMOs like Final Fantasy 14: Dawntrail drove revenue up even as mobile titles took a hit (RIP Kingdom Hearts Missing-Link), leaving digital entertainment sales down 18% but operating income up 28%. Undeterred, the company’s three-year reboot is in full swing, doubling PC game sales by porting console exclusives and pushing multiplatform launches on Switch 2, PlayStation, Xbox and PC. Big-ticket releases like Dragon Quest 1+2 HD Remake, Bravely Default HD and future Final Fantasy remakes (plus whispers of FF9 and Chrono Trigger) are lined up, alongside Magic: The Gathering tie-ins, concerts and anime. Expect a quieter fiscal year without a major Final Fantasy drop, but healthy profit growth looks likely.  ( 3 min )

TL;DR: Amazon’s Audible is tapping into its AI chops to churn out more audiobooks faster. Starting now, select publishers can either hand over their titles for Audible-managed AI narration or grab a self-service toolkit, choosing from 100+ AI voices across English, Spanish, French and Italian (complete with accents and dialects). Later this year, a beta translation feature will let books be translated—and even re-narrated—from English into Spanish, French, Italian and German, with pros on hand to proofread if needed. Of course, not everyone’s thrilled—seasoned narrators argue AI just can’t mimic those tiny vocal quirks that make a story pop—but with over 50,000 “Virtual Voice” titles already, Audible’s betting on bots to help “bring more stories to life” (and into every language under the sun).  ( 3 min )

Recently I got this DM, “Which tech stack should I learn?” “Should I use Next.js or Svelte?” “Is Python better for the backend than node?” I am sure we have asked or been asked questions like this several times in our tech journeys. As someone who is just starting out, I think it seems like a very important thing to ask. You don’t wanna waste your time learning a technology that might become worthless soon? Or isn’t fast enough? or isn’t the “industry standard”… right? Or should it matter? Back in 2003 when Facebook was originally founded, its backend was written in PHP. Was it the lack of options? You can say so. Back then they certainly didn’t have a plethora of frameworks or hell even languages to choose from. But what about now? Realistically PHP should be dead by now… Right?

Kotlin is a modern programming language that has gained popularity for its concise syntax and interoperability with Java. As I've been exploring Kotlin, it's come to become my favorite programming language. I built the benchmarks application in Kotlin, and included Kotlin as one of the languages it compares against. In this post, I want to share my thoughts on Kotlin's performance and how it compares to other languages. Kotlin JVM ranks last. And it's not close. At first, I thought this was a fault on my part. Maybe I was measuring the wrong thing, or maybe I was using the wrong libraries. But after some investigation, I found that Kotlin's performance is consistently lower than the rest of the languages in the benchmarks. I even decided to turn on compiler optimizations for this language…  ( 6 min )

Hi guys, welcome to my new post, we're talking about my next-gen of API graphics. Performance Material The Data Set is where all data: Shape, color, Dioprime, light...

You can setting it we -100 to 99 is left; 0 is between and 1 to 100 is right. Light until the next (because we'll talk about physics and time-lapse (science). Reference It stores all data in a nickname, but you're asking what the difference between Data Set and References is in the structure. Data Set, call all data and prepare it (which takes RAM if heavy), but the reference is just the nickname and setting of every data, it charges very fast. We have: S(Shape); M(Map); A(Appearance); D(Dioprime); E(Emissions) and V for verification, every reference should be in order if otherwise it's happen an Error of syntax too of you do recurtion which take time to get the solution.

Are you enjoying working with your favorite coding agents (GitHub Copilot, Cursor, Claude Code, OpenAI Codex, ...etc.) ? Even these agents are getting faster and faster, you'll often find yourself waiting for them to finish their work. Editing your code while agents are working will confuse them. So, is waiting all you can do? If you use git-worktree, you can do all of the following while your agents are working: Fix another pull request to respond to your colleagues' code review Fetch your colleagues' pull request and review locally Tackle other issues Work on documentation or tests in a separate branch Handle urgent bug fixes Let one agent generate code in one branch while you review another agent's output in a different branch git worktree lets you check out multiple branches into separate directories simultaneously. Unlike git checkout which switches your entire working directory, worktrees create additional working directories that all link back to your main repository. The main benefits: Work on multiple branches at once without stashing/committing Each directory has its own independent state All worktrees share the same Git history (efficient storage) Perfect for parallel development workflows # Create a worktree for an existing branch git worktree add ../feature-login feature/login # Create a new branch and worktree in one command git worktree add -b fix/api-error ../api-fix main # List all your worktrees git worktree list # Remove a worktree when done git worktree remove ../feature-login Remember that .env files and other files in .gitignore won't be copied to new worktrees. Copy these manually when needed. By combining git worktree with coding agents, you unlock a truly parallel development workflow. While agents are busy generating code in one directory, you can be productive in another. This approach eliminates idle waiting time and maximizes your productivity.  ( 3 min )

TL;DR Getters and setters allow you to control access to class properties. Setters are used to validate and sanitize data before it’s stored. Getters are used to control how data is returned — sometimes hiding or formatting sensitive information. It’s a way to encapsulate logic and protect internal state, especially when working with classes. The question that could save your car from flying off at Eau Rouge: how do I protect my classes in JavaScript? We’ve already walked through the power of this, constructor functions and classes, and one of the main reasons I use to justify classes was Security. As Uncle Ben once said (probably to a junior dev): "With great power comes great responsibility.".

And if you can't see what’s happening inside them, you're flying blind. In this episode, we’ll integrate OpenTelemetry with our ASP.NET minimal API and trace everything from database calls to cache hits — all visualized in Jaeger. We’ll also learn how to spot inefficiencies, validate cache behavior, and instrument our code for insights. Here’s why: Traces help you understand how requests flow across services (and through layers like DB, cache, etc.). Metrics provide high-level health signals like request rates and error counts. Logs give you contextual breadcrumbs when something breaks. In this episode, we’ll focus on distributed tracin…  ( 7 min )

Welcome, aspiring code wizards and seasoned developers alike! Today, we embark on an exciting journey into the heart of Ruby, a language renowned for its elegance, developer-friendliness, and its pure embrace of Object-Oriented Programming (OOP). If you've ever wondered how to build robust, maintainable, and intuitive software, OOP with Ruby is a fantastic place to start or deepen your understanding. At its core, Object-Oriented Programming is a paradigm based on the concept of "objects". These objects can contain data, in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). The main idea is to bundle data and the methods that operate on that data into a single unit. Why is this cool? Modularity: OOP helps you break dow…  ( 20 min )

Introduction Hover effects are a fantastic way to enhance user interaction on a website, and the circle hover effect is particularly eye-catching. If you've been trying to recreate the cool effect seen in the example link you provided, you're not alone! Many developers struggle with the timing and scaling of hover animations. This article will guide you through the creation of this effect using HTML, CSS, and JavaScript. Understanding the Circle Hover Effect The circle hover effect usually consists of an animated circle that expands outward from the point where the user hovers over a button or link. This effect not only captures the user's attention but also provides a more interactive experience. Why Timing Matters One common issue is the timing of the scaling effect where it may expand t…  ( 5 min )

Introduction: What is AGUI? Agent-based Graphical User Interfaces (AGUIs) represent a paradigm shift in how we interact with software. Unlike traditional GUIs where users must learn specific workflows, locate buttons, and navigate menus, AGUIs introduce an intelligent layer that understands user intent and completes complex tasks across multiple applications autonomously. At its core, an AGUI consists of three components: A natural language interface (text or voice) An AI agent that understands context and intent The ability to manipulate traditional GUI elements programmatically Think of AGUI as the evolution from "I need to figure out how to do X with this software" to simply stating "Do X for me" and having the system handle the implementation details. As developers, here's how we ca…  ( 6 min )

⚠️ This blog is opinionated. Please read with an open mind. You don’t have to agree, but if it gets you to pause and think, it has done its job. We buy jewellery to show off. It makes sense because jewellery is valuable. It shines, is admired, and can even increase in value over time. But code? Code is not an asset. It’s a liability. It gets outdated, collects bugs, and needs constant maintenance. But we still write it like it's something to be displayed — fancy, complicated, and a true legacy. I’ve seen code that could have been done in just a few lines, but instead, it’s spread across hundreds of lines and many packages. We create interfaces for no reason, factories for objects that are only used once, and layers of abstraction that make the code hard to follow. It often starts with simp…  ( 7 min )

Building apps that work offline isn’t just a nice-to-have anymore, it’s essential. Network issues are real, especially in places with unstable connections. Whether it's users in low-connectivity areas or those who just want snappy experiences, handling offline gracefully is one of the most impactful upgrades you can bring to your mobile app. In this guide, we'll walk through how to build an offline-first experience in a React Native app using Expo, GraphQL (via Apollo Client), and efficient local caching strategies that help your app shine even when the connection doesn’t. Users expect apps to "just work," even when the internet doesn’t. An offline-first approach ensures that your app can not only read data when offline but also queue mutations while offline and sync when back online. Here…  ( 5 min )

Ever wondered what an API is? Let's break it down with waiters, crayon drawings, and simple explanations. Perfect for beginners! Following up from my last post: 🧱 Git & Version Control — Explained Like You’re 5 (But Smarter) Now, let’s talk about APIs — using restaurants, crayon drawings, and kid logic. You walk into a restaurant. You're hungry. You don’t barge into the kitchen, right? That waiter? That’s your API. API = Application Programming Interface In simpler terms: It’s how one app talks to another — asking for things, sending stuff, or checking info — all without you needing to see the mess behind the scenes. Think of it as a messenger or a... well, a waiter! Let's break down that restaurant scene: You (the app): “Hey waiter, I want tomato soup.” API (the waiter): “Got it!” …  ( 5 min )

"Have you ever been so reliant on a tool that you forgot how to function without it? Yeah, me neither... until I met Gemini." Okay, so, recently, I think some of you might have experienced something quite similar - there is some kind of issue regarding the clipboard functionality of Gemini Pro. I must admit that Gemini/ChatGPT has become a deeply integrated part of my life so much so that I stopped working on my current showcase project when the copy-and-paste feature wasn't working. I felt...stuck. Yeah, I know it sounds silly now when I say it out loud, but for a few days, I didn't touch the coding (plus, I was also dealing with something on the personal front).

Wanted to create a listing but still have not? Lets break down the concept of listings, top platforms and their advantages and disadvantages to consider. As a person who has performed analytics for a few leading companies of today, I have never touched the topic of listings and its importance until today. However, I find it crucial, especially for someone opening a world of business possibilities and crypto projects. Listings refer to the inclusion of a crypto asset, such as a token or a coin on crypto exchanges. Just right after the company goes public, a crypto project seeks listing on a reliable platform with a positive reputation. Why is it an important step for projects to list their crypto assets? *Lets take a look at the most common platforms to list a token: Gate.io, OKX, Bybit, M…  ( 7 min )

I love self hosting. I run a Docker hosting platform that empowers everybody to self-host. I think every developer should know how to deploy their own stuff. But even I have limits. There’s a point where self hosting crosses the line from "empowering" to "why are you doing this to yourself" Not everything needs to be run on your 5 dollar VPS. Some things are best left to the hyperscalers or literally anyone else but you. So here’s my hit list: 5 things that in my opinion should be illegal to self host unless you're doing it purely to learn or you run your own continent.

The modern publisher’s tech stack is complex. Between header bidding wrappers, real-time auctions, analytics pipelines, and constant pressure to maintain site performance, it’s easy for monetization opportunities to fall through the cracks. Yet, for many teams, meaningful revenue growth doesn't always require new demand partners or sweeping changes. Sometimes, it’s about tuning what already exists. Bid density, for instance, is one of the most overlooked levers in yield optimization. A large number of participating bidders might look impressive on paper, but not every one of them adds value. When several low-performing SSPs flood your auction with low bids and timeouts, they create latency and drag down the overall performance of your stack. Instead of chasing quantity, publishers should a…  ( 4 min )

Introduction Modern applications often consist of multiple components written in different technologies. Companies using microservices, multi-layered systems, or external integrations face the challenge of testing business logic spread across various environments. Standard approaches require either running unit tests separately for each technology or simulating application behavior by mocking its functionality. However, such methods do not always provide a complete picture of the system's actual operation. With Javonet, it is possible to directly invoke classes from one technology within another and test them as an integral part of the system. This means that unit tests executed for the API can verify the actual behavior of individual components instead of relying on mocked responses. Th…  ( 4 min )

This mismatch can lead to issues with how Gradle resolves classes durin…  ( 4 min )

I still remember the first time I broke production. Not even a real change, just some code cleanup. What followed was a 40-minute Slack archaeology session, two failed deploys, and a DevOps engineer asking me why I didn’t “check the pipeline status”. What pipeline? Where? This was my first introduction to the silent chaos beneath most CI/CD setups. Fast forward a few years, and I’m not a DevOps engineer — but I am a developer who’s tired of treating CI/CD like some black box that either green-ticks or red-crosses your work. I’ve started to care less about whether a pipeline runs, and more about whether it respects my time, gives me clear feedback, and doesn’t feel like an act of penance to deploy code.

Table Of Content Introduction What is sudo? Why Use sudo? How to Configure sudo Access Best Practices Why Is sudo an Important Command? Summary One of the core principles of Linux is the separation of standard users and administrative (root) privileges.

I am creating a Java class and defining some methods that contain business logic. This class is annotated with @RestController, which makes it a REST controller in a Spring Boot application. Inside the class, I define methods and map them to specific HTTP requests. For example, I map a method that converts a name to uppercase using: @GetMapping("/uppercase/{name}") When an HTTP GET request is made to this endpoint (e.g., /vowelsController/uppercase/John), the method executes its logic and returns a response. Since this is a REST controller, the response is automatically returned in JSON (or XML) format, which can be consumed by a frontend application. Based on the returned data, we can design the user interface to display the output. When ever MVC (returns views like HTML)that we can use @Controller But REST APIs (returns data: JSON/XML) that we can use only @RestController  ( 3 min )

I've been working as a developer for a while now, mostly remote, across different projects and teams. Over time, I started to notice that the biggest improvements in my workflow didn't come from learning new frameworks or languages, but from small, boring habits. Here are a few that really helped me: Writing short and clear commit messages. Sounds basic, but it makes a huge difference when looking back at history. Naming variables like someone else will read them. Because they will. Taking 5 minutes before starting work to plan what I’m actually going to do. Not big planning, just a few lines in a notebook. Leaving small comments in code, even when I think “it’s obvious”. Future me usually disagrees. Closing Slack when I need to focus. Seriously. None of these are impressive or hard. But doing them consistently changed how I work and made collaboration smoother for everyone involved. If you're feeling stuck or overwhelmed, maybe it's not your stack — maybe it's just your habits. – Serguey Asael Shinder  ( 3 min )

As artificial intelligence chatbots have become ever more conversational, so too have their apologies. Polite, effusive, and sometimes all too swift, these regretful proclamations spill forth whenever an AI misinterprets a question, oversteps a boundary, or simply fails to please. But beneath their digital charm, a troubling question grows: when chatbots constantly apologise—with no true understanding of guilt or intent—are they learning merely to please, or are they being unwittingly trained in the art of deception? In the urgent race to make machines seem more “human,” are we accidentally teaching them to fake remorse, and if so, who does that ultimately serve? The apologetic AI is ubiquitous.

By Creator X Hi everyone — Creator X here. Today, I want to share how I started building Xion — not as some polished tech wizard, but as a solo developer learning as I went. It was a real life lesson. About five years ago, I built the first version of Xion as a simple online store using Wix. It worked… kind of. But it didn’t give me the flexibility I wanted — especially as I kept adding ideas and new content. So I scrapped it and started fresh. I experimented with a few AI tools and played around with concepts until I settled on a basic idea: project-based learning through building real things. At the time, I didn’t know much. But I did know HTML, CSS, and JavaScript, so I stuck with that. It was simple and fast. The backend was a bigger challenge, and honestly, the project got messy — to…  ( 5 min )

When I first started working on healthcare applications, one of the trickiest aspects was figuring out user permissions. Hospitals are loaded with sensitive data, and ensuring the right people can access the right information—without opening the floodgates—is a serious balancing act. That’s where Role-Based Access Control (RBAC) really shines. It’s a flexible, scalable system for defining exactly who can do what inside your hospital management software. If you're building a system that handles medical data, scheduling, or billing, this article will walk you through integrating RBAC the right way. RBAC is all about assigning permissions based on user roles instead of individual accounts. So instead of micromanaging every user's access, you simply define roles like “Doctor,” “Nurse,” or “Pat…  ( 4 min )

When developing Flutter applications, it's common to encounter scenarios where text needs to wrap properly within certain widgets. In this article, we will explore how to effectively wrap text in a Draggable widget in Flutter, ensuring that the text does not overflow but instead adjusts dynamically as it grows. This problem is often faced when using the Text widget within draggable areas. Here, we will dissect the example you've provided and offer a solution that addresses the issue. Understanding the Problem When your Text widget displays long text, it might overflow off the screen if it doesn't have proper constraints to wrap the text within its boundaries. The root of the problem often lies in the usage of the Text widget and how it is positioned within the Draggable component. You also…  ( 5 min )

In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them. Tracing is the most common type of garbage collection – so much so that "garbage collection" often refers to the tracing method, rather than others such as reference counting – and there are a large number of algorithms used in implementation. Tracing collectors are so called because they trace through the working set of memory. These garbage collectors perform collection in cycles. It is common for cycles to be triggered when there is not enough free memory for …  ( 4 min )

The badge isn’t the point—practice is. Over the past three years I earned every AWS certification. My certification triathlon study loop was simple: Watch one AWS Black Belt video on the target domain Drill through domain-specific question sets Review every miss (and every hit) the next morning That tight loop carried me across the finish line for every exam. I think the answer is yes—at least for your first rep. Buy a car, and suddenly you see the same model everywhere. Certifications work the same way: once my head was packed with VPC quirks and Lambda limits, blog posts, conference talks, and even hallway chats lit up with “Hey, I know this!” moments. That learning tuned my attention, and it wasn’t limited to AWS services; even general foundational computer-science concepts started jumping out at me. A skill sticks after three meaningful reps, even if the first one happens on paper. Because AWS exams don’t include a hands-on lab, Rep #1 takes place in the multiple-choice arena: you architect in your head, choose an answer, and a wrong pick costs nothing but a red X. Badge in hand, I volunteered for two bite-sized projects—Rep #2 and Rep #3—where whiteboard sketches became CloudFormation stacks and IAM policies. That’s when theory clicked into muscle memory. Certs don’t replace experience; they accelerate it. The exam delivers a low-risk Rep #1, and the New-Car Effect immediately tunes your radar—you start noticing tickets, hallway questions, and side projects that echo the blueprint you just drilled. Grab those chances: Rep #2 and Rep #3 will show up almost automatically, and the badge will turn into working muscle faster than any other route.  ( 3 min )

In the evolving world of Web3, non-fungible tokens (NFTs) have opened new frontiers for how brands engage with audiences. From digital collectibles to exclusive access, NFTs offer innovative ways to create experiences and loyalty. But before launching your NFT project, one major decision stands in the way: Which blockchain should you build on—Ethereum or Solana? Let’s compare both ecosystems through the lens of what matters most to brands: cost, speed, scale, and strategy. - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: Solana supports compressed NFTs, allowing brands to mint millions of NFTs cheaply on-chain. Ideal for: Customer rewards Digital badges In-game items Scalable loyalty systems Ethereum doesn’t yet offer an equivalent at scale—this gives Solana a clear edge for brands wanting to onboard users without friction. Choose Ethereum if your brand is aiming for exclusivity, luxury, or tapping into an existing high-value NFT collector base. Choose Solana if you’re focused on mass engagement, gamification, loyalty rewards, or experimenting with new, fast, scalable digital experiences. In the Web3 world, your brand isn’t just creating products—you’re curating experiences. Solana and Ethereum both offer unique value depending on your goals. The future of digital branding will be multi-chain, but choosing the right starting point can make or break your first NFT launch. Need help launching your NFT brand campaign on Solana or Ethereum?

I recently read this article that walks through some of the wildest, weirdest, and most iconic personalities in the crypto billionaire club. As a blockchain developer, I found it both entertaining and kind of surreal. These aren’t just wealthy people — they’re high-risk visionaries, meme lords, and sometimes, let’s be honest, chaos agents. Here’s a quick rundown of the madness — and what I’d invest in if I ever made it to that level. Founder of Binance, CZ built an empire that operates in almost every crypto sector imaginable. He’s not flashy — but his influence is massive. His “investment” is Binance itself: an ecosystem, an empire, and a global brand. Verdict: Ruthless focus over random luxury. Once hailed as the smartest guy in the room, SBF fell from grace after FTX collapsed. He poure…  ( 4 min )

I’ve been proudly learning C++ on and off for almost four years now. after successfully seg-faulting Node.js with a node api C++ program and getting hopelessly addicted to the language, I think I’ve earned some leeway to advise on how to learn it. C++ is a beast – metaphorically AND literally. It’s so large that 7 days into a head-first deep dive, I’m still discovering new things. but once you learn "enough" of it, you can do some ridiculously cool stuff… with a huge chance of "shooting your leg off" in the process. It’s the bloodline of AAA games, game engines, and critical runtimes like Node.js. Want to get closer to the kernel? Embedded systems? AI can’t…👀 vibe coders can’t… That’s power.

I’ve followed the classic React Tic-Tac-Toe tutorial enough times to finish it in my sleep 😅. Today, let’s build the same game in Vue. Along the way, you’ll see how Vue’s props, emits, reactive arrays, and computed properties map to (and simplify) React patterns like callback props, immutable state updates, and useMemo. Each cell shows a value ('X', 'O', or blank) and notifies its parent when clicked. In React, You pass an onSelect callback prop down the tree and call it on click: {value} Vue inverts this: children emit events, parents listen. In React, you lift state up f…  ( 6 min )

The World Health Organization (WHO) officially recognized burnout as an occupational phenomenon, defining it as: "a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy." But let's be real, fellow developers. Doesn't it feel like something… more?

This feature has been deployed in the latest release of QuickieSticker — feel free to download and try it out! When I was first asked to implement multi-selection for stickers, I flat-out refused. I had barely used Grid, didn’t know how to adapt multi-selection for it, and besides, the app’s existing functionality conflicted with Grid’s built-in multi-select, so I just deleted it altogether. As a result, sticker multi-selection had always felt like a technical challenge I’d been avoiding. It wasn’t until I was filming the promo video and needed to batch edit sticker info that I realized multi-selection was actually a very real need.

In today's digital age, software doesn't just have to work - it has to last. Companies are increasingly investing in long-term solutions that can evolve with changing needs. That's where cloud services come in. It's no longer just a buzzword. It's quickly becoming the new standard for ensuring software stays relevant, secure, and scalable over time. Before we dive in, let's define what we mean by cloud maintenance. So why is cloud computing getting so much attention? To understand how cloud services work, it's helpful to review their basic principles: Microservices architecture. Instead of a single block of code, applications are broken down into smaller, independent services. Each service handles a single task. This setup makes updates and debugging much easier. If one component fails, the entire system doesn't fail. Containerization. Containers (like Docker) package software with everything it needs to run. This makes deployment consistent across environments. It also makes it easier to scale and roll back if something goes wrong. Continuous monitoring and logging. Real-time monitoring helps teams identify issues before users do. Logs provide detailed information, making it easier to troubleshoot and optimize performance. Automation and CI/CD pipelines. Automation is the backbone of cloud service. CI/CD tools automatically push changes through the testing and deployment phases. This reduces human error and speeds up development cycles. Infrastructure as Code (IaC). With IaC tools like Terraform or AWS CloudFormation, teams manage infrastructure using code. This makes environments repeatable and easier to update or patch.

Drag-and-drop is one of HarmonyOS’s standout features. Since HarmonyOS 4 introduced the Data Transfer Station and enabled drag by default on the Image component in NEXT, it’s clear that drag gestures are being heavily promoted. Therefore, learning how to configure drag-and-drop properly is essential! HarmonyOS already provides a set of components with built-in drag-and-drop support, including Search, TextInput, TextArea, RichEditor, Text, Image, and Hyperlink. These components require checking whether the draggable attribute is set—if set to true, drag events can be triggered. A well-known example is the Bilibili feature where you can "drag out" characters 22 and 33—that works because their Image components have draggable set to true by default. To initiate drag behavior, the key is to imp…  ( 4 min )

After a period of development, ArkTS and ArkUI have moved beyond the stage of merely borrowing strengths from other frameworks.

I originally posted this post on my blog a long time ago in a galaxy far, far away. Want to be ignored on Slack or Teams at work? Type "Hello, how are you?" and press enter. You'll get ignored immediately. Especially if you're working in a remote team with people all over the world. And especially if you're reaching out to a busy manager or executive. Hello, how are you? ... Good, thanks. And you? ... Good too, thanks. Hey, I just wanted... But, what if your recipient is on the other side of the world? 24 hours could pass between each message. And for sure, you don't want to wait 48 hours to start the real conversation. While working remotely at a past job, I used nohello.net as my Slack status. That page shows a fake "hello, how are you?" conversation, getting ignored. And I still got "Hello, how are you?" messages. Arrrggg! I know you wouldn't. Then, why do the same on Slack or Teams at work? Next time you want to reach out to someone at work: Don't just send "Hello, how are you?" Say hi and in the same message, without waiting for an answer, say what you really want to say. Let me say that again, in the same message, without waiting for an answer. That should be "Remote Working 101" when onboarding new team members at any remote company. Starting out or already on the software engineering journey?

Let’s explore how to implement a custom marshaler in Go to handle this effectively, ensuring that your specific use case can accommodate hexadecimal encoding instead of base64. Why This Issue Occurs The default behavior for handling bytes in gRPC-Gateway is to convert them into base64 later when transforming them into JSON. This decision can be frustrating when hexadecimal re…  ( 5 min )

One major feature of Javascript is it is a single-threaded environment; it can only execute one task at a time. When one function calls another, the JavaScript engine carefully tracks these calls using a mechanism known as the "call stack."; A data structure that follows the LIFO (Last In, First Out) principle, a function call is added (pushed) to the top of this stack. When the function, and removed (popped) from the stack when the function completes its execution. Imagine the call stack as a tower of tasks, where each new function call adds another level to the tower. function greet() { console.log("Hello!"); sayName(); console.log("Goodbye!"); } function sayName() { console.log("Ny name is David."); } greet(); When this code runs, the engine first places greet() on the call s…  ( 7 min )

Creating a dynamic and consistent chart area is essential when developing a website that showcases data by region. If you're facing an issue where the chart's appearance varies based on the magnitude of the data, you're not alone. Understanding the Problem When you use libraries like Chart.js to visualize data, the space allocated for the y-axis can change depending on the scale of your data values. For instance, larger numbers may create more left-side margin space, inadvertently altering the chart's shape and making comparisons less intuitive. This is especially evident in your provided images where different datasets create discrepancies in chart sizing. Why Does This Happen?

Amazon ECS (Elastic Container Service) has just rolled out support for Amazon EBS Provisioned Rate for Volume Initialization — a powerful feature that speeds up EBS volume readiness when attaching from snapshots. This update is a game-changer for ECS workloads like: 🧪 ETL pipelines 🎞️ Media transcoding 🤖 Machine Learning inference With this enhancement, ECS tasks and services on both Fargate and EC2 launch types can now attach fully-performant EBS volumes right from the get-go! Previously, you could initialize ECS task volumes from EBS snapshots using snapshot-id, but performance was not guaranteed right away — data restoration from the snapshot could slow things down. Now, with Provisioned Rate for Volume Initialization, you can: ✅ Specify the initialization rate when creating volumes from snapshots In real-world production scenarios, time is money: ⏱️ ETL jobs don’t wait — they need volumes ready instantly 📺 Media processing workloads are time-sensitive 📦 ML inference needs low-latency, high-throughput disk access By provisioning initialization rates, you reduce startup delays and ensure consistent performance across containers. Define EBS volume attributes (size, type, IOPS, throughput). Attach volume to ECS task using a snapshot (snapshot-id). Specify the initialization rate during provisioning. ECS ensures attached volumes are fully-performant on task launch. ✅ Amazon ECS on Fargate ✅ Amazon ECS on EC2 ✅ ECS Tasks and Services You can also set this rate in ECS Task Definitions or Service Configurations, making it easy to standardize performance across deployments. This update from AWS bridges the gap between fast EBS volume access and containerized workloads. If you’re building data-intensive, high-performance applications on ECS, it’s time to take advantage of predictable storage performance with Provisioned Rate Volume Initialization.  ( 4 min )

Introduction Creating a user-friendly interface is essential in any application. When working with SwiftUI, you may want to enhance the usability of forms, particularly in a macOS application. In this guide, we will explore how to modify a grouped-styled Form to make a button that spans the entire row, allowing for smoother interaction. Our example involves managing a list of names, where we want the "New Person" button to be fully clickable, similar to List buttons in iOS. Understanding the Issue In SwiftUI, when you use a basic Button within a Form, it might not visually match the expected behavior found in List. Users often expect a row to be clickable throughout, not just the button area. To achieve a consistent feel with the functionality provided by NavigationLink, we need to use an …  ( 4 min )

Introduction If you're working with TypeScript, you might encounter a situation where you want to convert a union type into an enum for better organization and type safety. This is a common challenge, especially when trying to improve the maintainability of your code. In this article, we will illustrate how to achieve this conversion using clear examples. Understanding Union Types in TypeScript Union types in TypeScript allow you to define a variable that can hold one of several types. For example, consider the union type status: type status = 'start' | 'loading' | 'stop'; This means that any variable of type status can only be assigned one of those three string values: 'start', 'loading', or 'stop'. However, using union types can sometimes lead to a lack of organization, especially in la…  ( 4 min )

If you're new to containerization or just want a clear understanding of Docker, you're in the right place. In this post, we’ll walk through the what, why, and how of Docker in a simple, no-fluff format. 📦 What is Docker? Docker is an open-source platform that makes it easier to build, ship, and run applications using containers. A container is a lightweight, portable package that includes everything your app needs to run: source code, libraries, dependencies, and environment variables — all bundled together. Think of it like a “super zip file” that runs your code the same way on any machine. 🤔 Why Was Docker Needed? Before Docker, developers faced the classic: "It works on my machine" 😤 Apps would break when moving between dev, test, and prod environments due to OS differences, miss…  ( 4 min )

Let’s talk about something that’s been bugging me for years: the disconnect between how we design APIs and how we manage data. We throw around phrases like “API-first” and “decoupled architecture” like they’re magic spells. And yeah—they’re important. But too often, API-first ends up being endpoint-first... and model-later (or never). That’s a problem. A big one. 🎯 The Problem with Endpoint-First Thinking I’ve been on projects where we had beautifully documented APIs. Swagger UI, OpenAPI specs, even good versioning. But behind the scenes? No consistency across services Fields named three different ways depending on the team No central data structure—just whatever someone came up with on the fly Eventually, we were duct-taping together integrations and trying to reverse-engineer payloa…  ( 4 min )
